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

TOOLS REQUIRED:
• Inch and metric sockets
• Inch and metric combination and
open-end wrenches
• Pliers
• Wire cutters
• Scissors
• Drill motor
•1⁄8” drill bit
•13⁄32” drill bit
•7⁄16” drill bit
• Tap handle
•1⁄4” NPT tap
• Foot-pound torque wrenches
• Penetrating oil or light lubricant
spray
• Anti-seize compound
• Heat gun
1. Before starting work, familiarize
yourself with the installation procedure
by reading all of the instructions.
2. The exploded views provide only
general guidance. Refer to each step
and section diagram in this manual for
proper instruction.
3. Throughout this manual, the
left side of the vehicle refers to the
driver side, and the right side to the
passenger side.
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
blocked securely.
CAUTION: Do not use floor jacks to
support the vehicle while working
under it. Do not raise the vehicle
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.

1. Disconnect the battery ground
cables from each of the batteries.
Secure the cables so that they do not
come in contact with the battery posts
during the installation.
2. Clean the top of the fuse box
cover located on the drivers’ side of
the engine compartment. Make sure
the outside of the fuse box is free of
oil, grease and dirt. Place the Banks
Six-Gun Tuner on top of the fuse box
cover. Direct the wire harness towards
the front of the vehicle as shown in
Figure 2.
NOTE: The Six-Gun Tuner will be
affixed to the top of the fuse box in a
later step.

3.Locate the two black wire harness
locking connectors between the
brake fluid reservoir and the air
conditioning compressor. Lift the gray
connector locks and disconnect the
38-pin connector pair and the 24-pin
connector pair. See Figure 3.
NOTE: Remove the wire harness
retainer to facilitate in connecting the
38 and 24-pin connectors.
4.Insert the male 38-pin connector on
the Six-Gun harness into the female
38-pin connector on the factory
harness. Insert the female 38-pin
connector on the Six-Gun harness
onto the male 38-pin connector of the
factory harness. Repeat this process
with the 24-pin connectors. See
Figure 3.
5. Go to the air box and remove the
stock Mass Air Flow (MAF) connector
located on the elbow of the air box
cover and set aside. Loosen both hose
clamps on the air intake tube and
remove the air intake tube and set
aside.
6.Locate the MAF connector from
the Six-Gun Tuner harness and route
as shown in Figure 4. Follow the
factory harness located on top of the
engine that runs in front of the intake
manifold and behind the alternator.
Feed the connector under the
compressor outlet and under where
the air intake hose normally rest. See
Figure 5.
7. Connect the Six-Gun tuner’s
(female) MAF connector to the factory
(male) MAF sensor and connect the
factory (female) MAF connector to the
Six-Gun’s (male) MAF connector.
8. Reinstall the previously removed
air intake hose and tighten the hose
clamps.

9. Locate the rubber grommet on the
driver’s side of the vehicle firewall.
The grommet is about 3” in diameter.
Make a 1” x 1” cross-shaped incision
in the grommet (see Figure 6).
10. Now from inside the cab locate
the grommet on the firewall and make
another 1” x 1” cross-shaped incision
on the grommet. Feed the three-
connector cable through the incision
made in the firewall grommet and into
the cab.
11. With the Six-Gun Diesel Tuner
positioned on top of the fuse box,
peel the protective backing from the
hook and loop interlocking fasteners
attached to the Six-Gun Diesel Tuner.
Position the side edge of the Six-Gun
Diesel Tuner to the edge closest to the
engine of the fuse cover, then press
the adhesive onto the outside of the
fuse box cover. Apply light pressure to
the Six-Gun Diesel Tuner by hand for
60-seconds to create a strong bond
between the fuse box and hook &
loop interlocking fasteners. Using the
supplied cable ties, secure the wire
harness away from any heat sources
or moving components.
NOTE: Make sure the fuse box cover
is clean and free of any oil residue and
contaminates. Clean fuse box cover
with a non-oil based solvent such as
Acetone, Mineral Spirits, Denatured
Alcohol or Lacquer Thinner. Read and
follow the manufactures operation
instruction for non-oil based solvent
cleaner.
WARNING: Make sure to place the
tuner as shown in Figure 2 to avoid
a clearance issue when closing the
hood. Mount the Six-Gun Tuner as
close to the inside edge of the fuse
cover as possible.
