Banks Power Dodge Trucks: (Diesel ’03 - 07 5.9L Cummins) Tuner- Six-Gun Diesel Tuner w optional Speed-Loader Module, (325 HP Dodge 5.9L Cummins 600 (24-valve) Trucks) '04-05 For use with Six-Gun Switch - Manual (Page 23)

Note: the Six-Gun Diesel tuner requires
the engine coolant temperature (eCt) to
be above 125º before it will add fuel.
Note: this verification of proper
performance should be performed prior
to permanent mounting of the Six-Gun
Diesel tuner as illustrated in Section 7.
If DynaFact
® gauges are installed,
observe the operation of the boost and
pyrometer gauges 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 for
the Dodge/cummins diesel 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 pyrometer 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.
Your pyrometer is color coded to assist
in your reading of the gauge. The red
zone indicates a dangerous level of
temperature. Your engine should not
operate in this range for more than a
few seconds. The blue zone indicates
when it is safe to shut the engine off.
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.
