Tunes available to produce anywhere from 40HP economy/tow, 70HP Perf tow and more. While economy gains cannot be guaranteed, the economy tune has been producing very consistent mpg numbers at around 19-20mpg and sometimes more for single wheel trucks. Smooth shifting, low EGT's and more power/response than many 80 and 100HP rated generic tunes.

Installation Instructions

Tunes available to produce up to 150-200RWHP gains while still remaining tame enough to act as a daily driver. Smooth shifting, lower EGT's, and more power/response than many higher claimed generic tunes.

Installation Instructions

All tunes are built as dual mode switchable but as these vehicles age I recommend not adding a switch. The tuning will default to the lower HP level which should be plenty safe for a stock transmission. The higher HP will push the limits of the stock transmission. Typical tune sets are 50 HP econ/tow and 80 HP performance tune. While I make no claims or promises, the 50HP economy tune has been producing very consistent economy numbers at around 19-20mpg and even higher for single rear wheel trucks. DSP2 switch sold separately.
