I will be getting my dad's 01 duramax in a few months and after getting a rapid flow exhaust or putting a straight pipe on it, tranny upgrade, and intake upgrade I want to upgrade the motor. I am not sure what to go with either stacking the Quad 215 and the hot juice or just going with the PPE Xcelerator. I will need to be able to tow large equipment for my dad's excavating business, but also want to be able to stomp on it and smoke some guy in a BMW. Any other suggestions on programmers or chips are welcome.

Thanks in advance

If I were in your shoes, I'd probably go TTS Extreme after you build the trans.

Hot juice and quad or TTS.

Xtreme first choice, PPE second.

Does the PPE Xcelerator work on an 01? Or does it suffer the same quirks as a Quad?

The Main Quirk Is It Doesnt Remove The Limiter
