I am new to actually "tuning" a modified engine. I have used EFI Live to disable the VATS and other systems for engine swaps into older cars, but now I am wanting to actually help tune a 2001 vette. It has an aftermarket exhaust already and this weekend its getting a Fast 92 intake and TB. So where do I need to start tuning at.. I have been told to lean out the WOT to 12.7 for 20-30 HP gain. What other areas do I need to change for additional power gain.

PS its an automatic vette.

First correct the MAF and VE tables before leaning PE.

It is better if you post a log that has the afr in it. This way we can help.

If he's going to lean out PE for HP, then he should really be using a wideband to first correct the VE and MAF tables.
