Wondering if I could get some help.

I'm using 88590715 with MAF and for the most part everything is flawless, the only problem I'm seeing is a brief 2-3 second lean spike immediately after cruising when I lift off the throttle. AEM drops to 17-18 and car audibly struggles for a few seconds as the ecu compensates.

I'm trying to find the table that controls the ISCV as I lift off the throttle as I believe that may be the one I need to adjust but I'm just taking a wild guess.

Would I need to adjust the "ISCV Demand TPS Adder" tables?

 

The car should go lean if you let off the throttle in the 2,000-4,000 range.

 

Yes, but with the A/C on, it goes lean enough to almost stall and blip the oil light on the dash. With A/C off it does not.

It's a minor inconvenience but one I notice. Adjusting the "ISCV Demand TPS Adder" tables" slightly did not improve the issue, though I admit I may not have changed that table "enough".
