I just recently god a 2002 Procharged GT from my dad, and it is in desperate need of a tune. I was considering either Newtech or Nextgen Autosports, both of which are in Hayward. They both seem to use the Diablosport chips/predators, and both offer dyno-tuning at similar rates. Does anyone have experience with either shop? Anything positive/negative about either one? Thanks.
