496505 v.6.0
The Banks Six-Gun Diesel Tuner has six
power levels adjustable by the supplied
Six-Gun switch or the optional Banks
PowerPDA.
The optional Banks PowerPDA is a
versatile touch-screen interface to the
Six-Gun tuner and your truck that also
increases the Six-Gun’s power output.
With the push of a button, you can
change power levels on-the-fly just one
of the numerous Six-Gun parameters
Banks PowerPDA lets you custom-tune.
It displays four engine functions at a
time, two of which are user-selectable
(over a dozen to choose from). It will
clock your 0-60 mph, 1⁄8-mile and 1⁄4-
mile performance runs, recording peak
boost and EGT values. Performance
runs are automatically stored for later
retrieval with a time-and-date stamp.
With the Banks PowerPDA, you can also
scan and clear OBD II diagnostic codes.
It gives you the endless functionality of
a Palm®Tungsten™ E2 PDA, and fits in a
custom dash-mounted docking station
using infrared wireless connectivity.
The Six-Gun Diesel Tuner comes with a
Six-Gun switch that has six selectable
power levels. The Six-Gun switch is
included in the Six-Gun Diesel Tuner.
Level 1 is stock. Each additional higher
level adds approximately 20% of the
available power increase.
To prevent damage to the factory
transmission, Banks recommends
that both automatic and manual
transmission vehicles do not exceed
Level 4 while the vehicle is experiencing
load (towing, climbing a steep grade,
carrying a load, etc.).
To use the higher levels of the Six-Gun
Diesel Tuner while towing or climbing,
airflow improvements must be made
to lower the exhaust gas temperature
(EGT) entering the turbo. The EGT should
not exceed 1400º F for more than a few
seconds. Elevated EGT can damage the
turbocharger and the engine.
ATTENTION! Before proceeding with
these instructions, please carefully
read the DISCLAIMER OF LIABILITY
and LIMITATION OF WARRANTY
statement located on page 2 of this
manual.
WARNING: The PDA may be
susceptible to damage as a result
of extended exposure to sunlight,
heat or extreme cold. It is highly
recommended that the PDA
be removed from its mounting
location if the vehicle will be
subjected to high concentrations
of sunlight, heat or cold for
an extended period of time.
Gale Banks Engineering is not
responsible for damage to PDAs
resulting from exposure conditions

4. Disconnect the negative (ground)
cable from the battery (or batteries, if
there are two) before beginning work.
5. Route and tie wires and hoses a
minimum of 6” away from exhaust
heat, moving parts and sharp
edges. Clearance of 8” or more is
recommended where possible.
6. When raising the vehicle, support
it on properly weight-rated safety
stands, ramps or a commercial hoist.
Follow the manufacturer’s safety
precautions. Take care to balance the
vehicle to prevent it from slipping or
falling. When using ramps, be sure the
front wheels are centered squarely on
the topsides. When raising the front
of the vehicle, put the transmission in
park (automatic) or reverse (manual),
set the parking brake, and block the
rear wheels. When raising the back of
the vehicle, be sure the vehicle is on
level ground and the front wheels are

onto concrete blocks, masonry
or any other item not intended
specifically for this use.
7. During installation, keep the work
area clean. Do not allow anything to
be dropped into intake, exhaust, or
lubrication system components while
performing the installation, as foreign
objects will cause immediate engine
damage upon start-up.
8. Save this Owner’s Manual as a
reference for system maintenance and
service.
9. Banks recommends either a Banks
PowerPDA or a Pyrometer (EGT)
gauge and Boost gauge be installed
with the Six-Gun Diesel Tuner to help
monitor performance and exhaust
gas temperature of the vehicle (see
part numbers next page). To further
increase engine life by lower EGT’s,
Banks also recommends installing a
Monster Exhaust® system (see next
page).
General Installation Practices
Notice: A Pyrometer (EGT) probe must be installed in conjunction with
the Six-Gun Diesel Tuner in order to enable the Six-Guns EGT limiting
function. Using the Six-Gun Tuner without a pyrometer probe can lead to
detrimental damage to the engine due to excessive EGT temperatures.

INSTALLATION OF THE SIX-GUN SELECTOR SWITCH
Not needed if optional Banks
PowerPDA is installed.
CAUTION: Do not use force
when working on plastic parts.
Permanent damage to the part
might result.
1. The Six-Gun switch will be installed
on the driver’s side of the instrument
panel (IP) next to the steering column
(see Figure 10). Carefully remove
the IP from the dashboard by slowly
pulling outwards from the dashboard
around the edges of the IP, allowing
the mounting pins to pull free from
their dashboard sockets. Automatic
transmission equipped vehicles will
need to set the parking brake and
move the shift lever down to the
lowest gear to allow clearance for
instrument panel removal.
2. Cut out the supplied template
(see Figure 19 on page 31) and align
the template onto the rear of the IP,
squarely seating it on the top of the IP
mounting pin (see Figure 11).
3. Using a 3⁄8” Uni-drill bit, center the
bit onto the 3⁄8” drill location on the

template and any plastic shavings.
4. On the front side of the IP, align
the Banks Six-Gun label onto the
previously drilled hole (see Figure 12).
5. Remove the nut and internal tooth
washer from the Six-Gun Switch.
Rotate the shaft counter clockwise
until the shaft stops. Verify the locating
washer tab is inserted into the #6
position on the switch (see Figure 13).
NOTE: If the washer is in any position
other then the #6, your Six-Gun Diesel
Tuner will not select power levels
properly.
Figure 10

16 96505 v.6.0
6. After confirming the locating
washer is in the #6 location, install the
switch through the 3⁄8” hole on the
backside of the instrument panel. The
alignment pin should rest in the 1⁄8”
hole and with the switch fully rotated
counter clockwise; the shaft’s flat side
should be facing the steering column.
Secure switch with internal tooth
washer and nut. Snug the washer; be
careful not to over torque the nut and
damage the plastic threads.

1. The thermocouple monitors
the temperature of the exhaust
gases entering the turbocharger
at the turbine housing. Installation
requires that the exhaust manifold
be drilled near the manifold outlet.
It is recommended that the manifold
be removed from the engine to
thoroughly clean out all metal chips
from drilling. If manifold is not
removed from the vehicle, all chips
must be removed from the manifold.
This may be accomplished by using
a magnet to extract the chips after
drilling. The tap should be greased
before use and the chips again
removed with a magnet. All metal
shavings must be cleaned from the
manifold to avoid turbine damage.
2. To access the exhaust manifold,
remove front passenger wheel well by
removal of plastic retainers.
3. On the passenger side, remove the
hardware retaining the turbine inlet
exhaust pipe to the exhaust manifold
using a 12mm, 12pt socket along with
a 12mm, 12pt wrench, then remove
the exhaust manifold from vehicle. Pay
special attention to the orientation of
the manifold outlet gasket. Retain the
hardware and gaskets for re-assembly.
4. Center punch and drill through
the passenger side exhaust manifold
into the rear passage at the location
shown (see Figure 18). Use a 7⁄16” drill,
keeping the drill perpendicular to the
manifold surface.
5. Tap the drilled hole with a 1⁄4” NPT
pipe tap. Check the thread depth as
you tap by periodically removing the
tap and screwing the thermo-couple
insert into the tapped hole.
6. Install the thermocouple insert
into the manifold using anti-seize
compound on the threads. Install the
probe in the thermocouple insert.
7. Make sure to remove all shavings

NOTE: Please refer to the Banks
PowerPDA Software & Installation
Kit, Owners Manual for software
installation and operation instruction
before beginning Section 6, Automatic
Transmission Learning
The 6.6L Chevy Duramax Trucks
equipped with the Allison 1000 6-speed
automatic overdrive transmission use
an adaptive shift control logic. This will
require the transmission to adapt to
the additional power created by the
Banks Power products before it will
shift properly. Failure to follow the
sequence can result in damage to the
transmission.
Perform the following sequence at a
location where it is safe to accelerate
without exceeding the posted speed
limit.
1. Set Six-Gun to level one power
setting, start the truck and allow the
engine to reach normal operating
temperature.
2. Adjust Six-Gun to level two, power
setting.
3. Drive vehicle for 5 to 10 miles ensuring
a complete shift cycle though
each gear.
(The transmission shift adaptation learning
process requires 15 to 30 complete shift
cycles to learn new shift program.)
4. Increase power level by one and
repeat Step 3 until the desired power
level is achieved.
WARNING: Take particular care not
from inside the exhaust manifold.
Reinstall the exhaust manifold. Torque
to 28 ft-lb in the sequence shown
Figure 14.
8. Attach the thermocouple to the
supplied thermocouple leadwire
extension with the supplied nuts
and bolts. Cover this joint with the
supplied heat shrink tubing and heat
until the tubing conforms to the joint.
Make sure the entire joint is insulated.
9. Route the thermocouple leadwire
extension along the factory harness to
the driver’s side and connect it to the
Six-Gun harness with the supplied nuts
and bolts. Cover this joint with the
supplied heat shrink tubing and heat
until the tubing conforms to the joint.
Make sure the entire joint is insulated.
10. Reconnect the ground cables to
the vehicles batteries.
NOTE: Once the Six-Gun Diesel Tuner
is powered up at key-on, it will ‘learn’
that a thermocouple is installed and
automatically enable the EGT limiting
function.
If the thermocouple is removed
after being installed and run on the
vehicle, the Six-Gun Diesel Tuner will
assume that the sensor or connection
has gone bad, and cease adding
power while triggering the [2,3]
diagnostic code (see Trouble Shooting
Section 8). To ensure that the Six-
Gun Diesel Tuner operates properly
after removing a previously installed
thermocouple, see the ‘Clearing
Learned Information’ Section 9. EGT
limiting will not be operational and
excessive EGTs may develop at higher
power levels.

CHECKING ENGINE PERFORMANCE
to do wide open runs in 5th gear
when in Automatic transmission
Learning Mode, especially if speed
loader is installed.
The Allison 1000 6-speed automatic
transmission will continually adapt
to the power output of the engine to
optimize shift quality. The transmission
will quickly adapt to the power setting
if the driving cycle includes regular
gear changes at high loads. The
transmission learning procedure will
need to be repeated when switching
back to the higher power settings
once the transmission adapts to
the lower power settings. It will be
apparent when the transmission
adapts to the lower settings by
monitoring the feel of the gearshift.
Gear changes will be noticeably harder
when initially switching from a higher
to lower power setting. This will soften
as the transmission adapts to the new
setting.
-END, SECTION 5-
The Six-Gun Diesel Tuner requires the
engine coolant temperature (ECT) to be
above 110º before it will add fuel. If the
optional Banks PowerPDA or DynaFact®
gauges are installed, observe the
operation of the boost and pyrometer
(EGT) gauge values while driving under
varying conditions. Turbocharger boost
pressure will increase as a function of
load and engine RPM, thus the engine
will produce little boost while cruising
at light throttle, with maximum boost
while climbing hills heavily loaded during
acceleration. Note the boost level seen
during hard acceleration with a given
load. If performance seems to have
deteriorated sometime in the future,
the maximum boost figures may be
compared to see if boost has dropped
off. Lower boost may be caused by
turbo ducting leaks, a malfunctioning
wastegate or fuel injection pump, or
dirty air filter. Typical maximum boost
pressure settings will vary considerably
with stick or automatic transmission
options, year model of vehicle and
altitude.
NOTE: Before key-off, check tuner for
error codes. Use your Banks PowerPDA
or EGT gauge to monitor exhaust gas
temperature (EGT) in the engine. At
idle, exhaust gas temperature will be
very low, perhaps only 300°F. As the
engine is accelerated for higher speeds
with greater loads, the EGT will rise.
The highest EGT will be seen under
maximum load at full throttle, such as
climbing a steep grade with a heavily
laden vehicle. To avoid heat damage
to various engine components it is
recommended that the exhaust gases
cool below 400º before the engine is
shut down. Your Six-Gun Diesel Tuner
is calibrated to maintain a maximum
EGT of 1350°F. You may experience
brief excursions slightly above 1350°F
under acceleration. This is normal and
EGT should return to 1350°F or below
within a few seconds. If you find that
EGT remains high for any length of time,
check for boost leaks or a dirty air filter.
