Dear Customer,
If you have any questions
concerning the installation
of your Banks Six-Gun Diesel
Tuner, please call our Technical
Service Hotline at (888) 839-
2700 between 7:00am and
5:00pm (PST). If you have any
questions relating to shipping
or billing, please contact our
Customer Service Department
at [phone].
Thank you.
The Banks Six-Gun Diesel Tuner has six
power levels that you can adjust with
either the Six-Gun switch (supplied) or
the optional Banks iQ Dashboard PC
(sold separately).
Banks iQ is a versatile device that gives
you total control of your Banks Six-
Gun Tuner. With a touch of your finger
on the bright, full-color LCD display,
you can adjust power parameters, set
system warnings and alerts, see vital
engine functions at a glance, and more.
Evaluate your changes by running 0-60,
1/4, and 1/8mile performance tests. You
can even scan, read and clear OBD II
diagnostic trouble codes.
Banks iQ doesn’t stop there. It’s a true
in-car PC packed full of extra functions.
Listen to your favorite tunes, watch
videos, play games, review Windows®
Office documents, and more.
Expandable and upgradeable, it comes
fitted with a rechargeable battery and
includes accessory cords. You’ll quickly
discover Banks iQ is the device you’ll
use every day, both inside and outside
your car.
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.
The optional Speed-Loader module
can be added to the Six-Gun for off-
road use only to increase the power
output of Levels 2-6. Level 1 is stock
with or without Speed-Loader installed.
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 or Level 3 with optional Speed-
Loader 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.

output—this includes removal of
the 5th gear power de-rate, and a
raised EGT limit (to 1500 °F). With
a Speedloader installed, Level 6
should only be used in unloaded,
off-road conditions for short
amounts of time, NEVER on-road
or under heavily loaded conditions
where extremely high exhaust
gas temperatures could lead to
turbocharger and engine damage.
Warning: if excessive torque
converter slip is detected then
a Limp Home Mode override will
be set by the ECU. This LHM will
be active until torque slippage is
no longer detected or is reset by
Diagnostic Tool.

provides access to an additional power
level of the Six-Gun Diesel Tuner.
Installing the Speed-Loader will allow
levels 2 through 6 to experience an
increase in power above that of the
Banks Six-Gun Diesel Tuner alone.
Level 1 remains at stock power
output regardless if the Speed-Loader
is installed. Once the Speed-Loader
is installed and detected, the green
LED on the Six-Gun connector will
flash twice at power up. Refer to the
following “SPEED-LOADER LEARNING
SEQUENCE” section for more details.

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 14). 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
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

96815 v.1.0 19
Once the Speed-Loader Module is
installed or removed from the vehicle,
the following learning sequence will
need to be performed so that the Six-
Gun Diesel Tuner can correctly identify
that the Speed-Loader is present or
absent.
1. Start the engine
2. Turn the Six-Gun switch to the
highest level (position 6) and stay
there for five (5) seconds.
3. Rotate the switch to the lowest
level (position 1) and stay for five (5)
seconds.
4. Rotate the switch again to the
highest level (position 6) and stay
there for five (5) seconds.
NOTE: To determine if the Banks
Six-Gun Diesel Tuner is running the
Speed-Loader programming, watch the
GREEN LED on the tuner and turn the
ignition switch to the ON position (BUT
DO NOT START THE ENGINE). If the
GREEN LED flashes, the Banks Six-Gun
Diesel Tuner will run with the Speed-
Loader programming. If the GREEN
LED doesn’t flash, the Banks Six- Gun
Diesel Tuner will run the standard
programming. If the GREEN LED does
not indicate the same status as your
Six-Gun and Speed-Loader setup,
repeat the above steps.

Section 5
SPEED-LOADER LEARNING SEQUENCE
(APPLIES TO SIX-GUN SWITCH INSTALLATIONS ONLY)
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

Gun Diesel Tuner operates properly
after removing a previously installed
thermocouple, see the ‘Clearing

Section 6, Automatic Transmission
Learning
The 6.6L Chevy Duramax Trucks
equipped with the Allison 1000
5-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
to do wide open runs in 5th gear
when in Automatic transmission
Learning Mode, especially if speed
loader is installed.
The Allison 1000 5-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.
