Injectors are perfect. They fired/flowed/leak tested/ and matched perfectly. Talked to Aeromotive and the system dropping to zero isn't the issue either as that is the normal operation of the regulator being used. So... I have a tuning issue. For some reason my computer (which is showing to be out of a 2004 HD or Van with drive by wire and 4L80E) does not like the 2 bar map or my tuner isn't familiar with the truck setup - which I find very hard to believe with the number of tunes he does and how long he has been in the game doing them. When it gets to the tune part - it gets over my head. I am getting very frustrated. If I wasn't moving, I'd rip this PCM and Harness out ($700 harness) and throw Holley EFI on it and move forward.

Does anyone out there know of any issues relating to the truck ECM's OS in regards to the VE tables not responding to the 2 bar map properly?
