I am working on a 2001 Corvette.
Has an A@A Supercharger on it, 1 7/8" ARHeaders, Corsa Mufflers, Rest of the engine is stock.
60 lbs Injectors
Issue I am having is the car is really rich at Idle, I plugged in the Injector Data from A@A web page.
Doesn't seem to make any difference how much I pull out of the VE table, still pig rich.
I am hoping someone here could see what I am missing.
I capped off the SC, and looked for leaks with my smoke machine, didn't have any.
I did an Injector balance test with my tech 2, all seemed okay.
O2 wiring looks good, put new 02's in it, no change.
I did try to tune it the old school way, I left the factory INJ data in and just Changed the IFR to get the LTFT and STFT in shape, which seemed to work, except at very light load and throttle it had a stumble, car would go rich then very lean and then back to normal.
So now I'm back where I started, using the injector data and trying to the fuel trims sorted out and having no luck.
