The Predator has a "zero HP tune" but speed limiter raiser and tire,gear change calibration option ..... JP Customs is selling them at a decent price ...He is a registered vendor here ,check it out ...
For power stacking :
You have to be carefull what you stack .... Keep in mind the limitations of the Allison and or 6 speed clutch/flywheel ...
Also injector Pulse on Pulse width (as in Edge and most current boxes if not all ) give minimal gains .... In other words a 125 HP Edge Juice and a 100 HP Predator tune doesen't or wont yield 225 Rear Wheel Horse Power ... But might only add 20 ,30 HP in a stack of Pred on top of Juice ....
Same goes with say adding a 100 HP Duramaximizer on a Pulse box will only yield about 50 HP out back ... The Duramaximizer ups fuel rail pressure only .... The early Van Aaken (BD Power) boxes up fuel rail pressure as with timing also ... Not knowing what year your truck is,you have to be carefull playing with the pressure boxes with 01's ....
To much timing can also be a issue even stacking with Propane or bigger Pulse Timing boxes ...
Caution to the wind .... Not trying to discourage but be prepared and know what your signing on for ...
I run the most recent OJ and BD Power (no timing) as a daily driver .... Turning on VA only when I want plumes off smoke !!!!!
Gauges are a MUST !!!!!!!!! Heavy EGT'S and I can pin Boost gauge ,waste gate deprived .....
