What causes tip in?
When I am driving steady, 1500, 2000, 2500, and ease into the gas, the AFR (mounted in car) jumps to 17-18AFR briefly before returning to 14-15.
I am "retuning" my VE now (SD tune) but this seems to different issue

If your talking very briefly, I believe that is normal. It just takes a brief mili second for the ecm to adjust to commanded AFR. There are some settings that are map related I think off the top of my head that can contribute also.

What is your tune besides a SD tune? Is it na car or 2/3 bar enhanced?

This is more than briefly; It causes a noticeable delay
I am running a 2 bar tune. It is a blower car.
I am going to richen up the area in the VE table where I am seeing the lean issue (65-75KPA, 1500-2500rpm) by 10% ad see if has any affect.
Thanks

Are you talking like 15% throttle? Or more? It should hold steady around stoich if you're cruising or applying light throttle until you reach PE mode enrichment or boost enrichment.
