Your Six-Gun Diesel Tuner (with or
without the Speed Loader) needs to
know the correct power rating of your
engine in order to provide the proper
calibration and tuning. The correct
engine power rating can be found on
the tag in the engine compartment at
one of the locations shown in Figure
20. The power rating is typically shown
in the upper right hand corner of the
tag. The rated power should be 235,
250 or 305 hp. If the rating is different,
contact Gale Banks Technical Support.
Follow the steps described below
(Step 1 to 6) to teach your Six-Gun
Diesel Tuner the power rating of your
engine. As shipped, the Six-Gun Diesel
Tuner is calibrated for a 305 hp (High
Output) engine. If you have a 305
hp rated engine, skip to Section 7,
