What AFR are most of you running in your tune with zero Knock Retard on pump gas without using water injection. Also what boost are you running with this AFR? Are you keeping the AFR curve flat or are you running a leaner AFR to help spool time then richening it up as you approach redline?
I'm just trying to get my portfueler tuned safe with the agp 3147... Answers to these questions will help get me pointed in the right direction. I am currently tunned at 10.3afr @ 3200rpm and as I approach redline I get an 11.3afr, but I am also getting Knock Retard of 4 to 5 at redline. This is on pump gas at 18 to 19psi, and no water injection.
Thanks for any help you can provide!
