Hi guys, I'm new here and though I have 30+ years experience working on cars, I have zero tuning experience. I have a '95 Riviera that I built with and for my son. It has a Series 1 L67 3800 Supercharged motor and a 4t60e tranny. We need to start tuning this spring when the car comes out of storage and need to learn what's involved. I do have a pretty good knowledge of what makes a car run. Where I am lacking is in reading the info associated with tuning. Do I download Tunerpro RT and have at it, or do I learn first? Will downloading the free Tunerpro first to familiarize myself be a good idea? I don't want to get ahead of myself. Will it make more sense when I can see it? Your advice will be greatly appreciated! Thanks Dave
