[QUOTE="Lou02stang, post: 16619396, member: 177333"] I am tuning my single turbo 2v with SCT PRP. when doing a in park rev log 1500,2000,2500,3000,3500,4000 rpm. I am in closed loop the STFT are within 3% and no matter what RPM the AFR is reading lean. While idling the Trims are perfect and AFR is around 17.2. If it was a air leak before the O2 it should go away with higher rpm but the inconsistency is the same. I am return fuel twin 340 in tank with Deka 80 40psi Base. My fuel injector data is correct. What can be doing this [/QUOTE]
