Hi all, I have a early 04 5.9 QC (airdog 100 4x4 4.10 gears 295 BFG's trueflow air intake with gutted torque tube and a 50gal aux fuel tank )basically stock running a bullydog torquedog module for a few years now but want a little more giddyup and some smoke would be cool too. Anyone know exactly what kind of box this is? pressure ,timeing, boost, etc? not finding a lot of info on it out there. I'm considering a smarty or jr. when the budget allows and a turbo back exhaust in the near future. Any recommendations on boxes or can this box be stacked with any other system and still be "safe" for a stock auto trans. I always run this box on the high setting even when towing my toyhauler and sandrail and the EGT's hover around 1100K at the manifold.
