Does anyone know which aftermarket "box" actaully reprograms the TCM for firmer / quicker shifts? Or do they just let the TCM learn the new increased torque levels and automatically firm up the shifts. I see in the Juice / Attitude instructions, that it has a way to override the defueling during shifts. Does the Quad, Six Gun, TTS, etc.... reprogram the tranmission shifts firmness, or remove the defueling during shifts, OR do they all just let the allison try to protect itself from the increased torque levels ?????
My '04 is bone stock, but I want to add a box which also firms up the shifts some. I hate having to guess if it shifted or not
