Hi,
I got a "base tune" for a supercharged system from a reputable shop. Since the "base tune" was from -99 Vette and the actual car is -97, I copied what I thought to be relevant parameters (60 lbs injector info, VE, MAF, etc.).
For some strange reason LTFT's are now +25 and STFT's also around +35. I'm pretty sure that the injector info is spot on, as well as (stock) VE-table, since this is otherwise stock engine, apart from obvious Vortech supercharger system.
The fuel pressure is around 58 PSI and since this is -97, there is also regulator input from the intake (on front of the throttle body). I reseted fuel trims, but as soon as engine goes into closed loop, STFT's and LTFT's are quickly raising.
Could this be because of failed O2's? Or intake leak? I cannot believe stock engine would need a huge modification in VE to compensate supercharger in the idle.
Here's tune, scan and config attached:
