I'm working on the tune for my twin turbo TrailBlazer SS. I've got the boost turned down for now, and I've failed the MAF and I'm running SD only. While the tuning seems to be going fine for now, I'm having hard time hitting all the areas I want to on the street...and I'm thinking of buying some dyno time.
My question is regarding the factory tune for boost. In the VVE table, it looks to have numbers all the way to 3 bar. Now, assuming nothing else changed (injectors, engine internals, etc), how accurate are these numbers? Let's say the factory injectors were good to 14 psi (they aren't). If you could feed the motor with 14 psi and have it hold together (it wouldn't), would the numbers in the factory tune work?
