Re: 1995 C3500 454 OBD1 questions
I did a lot of prom burning with my TPI third gen camaro, then started to with my 89 TBI stepside. While I made improvements tuning it, it wasn't worth the effort compared to doing a carb/HEI swap. I never looked back. It was a pita. Scan while driving, upload data, analyze, make changes, burn new chip, drive and scan, upload, analyze, make changes, burn another chip, repeat, repeat, repeat. TPI could get to light right up without excessive cranking, TBI always seemed like a dry carb first start of the day no matter what I did. That was my biggest complaint. I used to use Tunercat and a pocket programmer II, but I think Jet bought Tunercat out. Life is supposed to get easier as we get older, not harder.
