[QUOTE="ctgreddy, post: 14179923, member: 122280"] ***EDIT*** Please skip to post 8 for my current problem! I've been trying to dial in my wot afr using sct prp. Around town I could only find a place safe enough to do 3rd gear pulls, so that's what I did and got it in the 11.3-11.6 area which I'm happy with. So I figured my car was good. A little bit after that I raced a buddy and noticed in 2nd/3rd the afr is were it should be, but in 4th it goes rich, like low 10's rich. Fast forward to today, I finally got around to getting on the highway later in the day with no traffic, so did some 4th gear logs. It's rich past about 5k rpms, like low 10's like I thought. So since it seems everyone dyno's/tunes the cars in 4th I figured I'd try dialing it all in again using 4th gear logs. I got it close and figured I'd try and do a 3rd gear pull, well wouldn't you know it anything in 2nd/3rd is lean now, right around 12.4 from what I saw before I let out. So wtf am I doing wrong?
