Well Im running a Miniram'ed 383 10.7 cr, with pocket ported TF 23* heads, TPIS ZZ409 cam with 1.6 rr, SLP shorty headers and Flowmaster 3" cat back exhaust, run off a GM 730 ECM. I had a 52mm TB on the car and just upgraded to a 58mm, so I was looking for a little direction on where I should go next for my tuning.

Ive done some searching but it dident turn up the results I was looking for. Im not looking for a "what do I do next" kinda thing, but more of good direction to get pointed to. Thanks in advance.

 

Mostly...set the min. air and IAC manually then check out the A/F ratio. Your timing won't change more than likely...just fueling.

 

I did set the TPS and IAC, and figured I would need to do some fuel trimming due to the fact that the TB is now letting in more air. I was not sure if I should hit the AE or the main fuel table.

 

In open loop, the VE needed to be changed a little but the AE was fine. Its more PE or 90-100 kpa.
