However, it was discovered by Trifecta that the ECM is not providing the right data based on the airflow read by the MAF so the computer moves into a "safe/limp" mode until the readings come back into range. Both STS and Trifecta believe that the current fuel injectors are capable to flow enough for the boost that I want to run. I was just sent a new tune so I'll be trying it out tonight. Keep your fingers crossed.
As far as 2 tunes, I should only need to run 1 tune. I know that N20 (e.g. Rod1) needed two separate tunes, however since the turbo is really just increasing the airflow, a single tune should be sufficient. At least that's what is expected right now.
I know its been said but Trifecta has been terrific to work with. The data logger has allowed the "mail order tune" process to work really well (actually e-mail). I currently have a Diablo Predator for my LS1 but will be purchasing a tune from Trifecta as I am sure he can tune the ECM much better than I can with the handheld Predator.

What's the diameter on your MAF housing?
