Hello,
I'm new to this board and I have a few questions. First, I don't have a F-body
but I do have a JBody. It's a 93 chevrolet cavalier z24 swapped with a 3400 and a custom made turbo setup. I'm running 8F code which is the code from the rare 89-90 TGP 3.1 turbo. I'm asking my question here since you seams to be the guys that know the most about GM tuning so far on the forum I'm reading. Here is my questions:
- Car is running pretty lean on decel right now, which "decel enleanment" table i could modify to fix that ?
- When coming to a stop, the rpm is stuck at like 2k rpm until I'm completly stopped. It seams to be worst when cold. Is there a table "IAC position vs MPH" or something like that which could fix my isssue ?

I don't know how much this will help you but I have a similar problem with the idle issue on my bird and just found this in a search.
