Main Screen
The main screen will give you two options to
choose from:
DOWNLOAD – Select this option to download a
power program, remove the vehicle’s speed
limiter, adjust tire size for the speedometer, or to
return the program to stock.
DTCs – Select this option to view and erase
diagnostic trouble codes.
Download Function
Highlight the downloader option from the main menu, and press the Y key.
If this is the first time you’ve used the tuner, then
the downloader will then read and save the
vehicle’s stock information. This procedure will
take 5-7 minutes.
If this is not the first time you’ve used the tuner,
then it will read and verify your trucks information,
and then proceed to the tuning menu.
Once the save/read is complete, the downloader
will display a list of available power settings. Use
the up/down arrows to move through and select a
power program.
Refer to the Power Settings chart on page 3 for
more information on available power levels. Using
the “Factory” power level returns the truck to
stock, or leaves the OEM settings intact if the
truck has never been programmed.
