2008 Trailblazer SS E67 that we installed a 6.2, has long tube headers, cold air intake through inner fender, Tick stg2 TowMax cam, 80lb injectors, tow converter, sheet metal intake, 102mm throttle body and is currently running. Reason for throttle body is original one had damaged plug and I had this one laying around. I'm okay with getting GEN3 stuff fairly well but this VVE has me pulling out my hair. Previous tuner made the truck run absolutely horrible where we believe it washed down the cylinders. I started with a completely stock Trailblazer file and did the injector data, scaling and it starts better then before and seems to idle fairly well but needs professional help for sure. I have tried calling James Pruitt, D Steck, super nice but not doing remote tuning. I'm hoping for either help or good recommendation for remote tuner please.
