3rd geat pull ,didnt take it to redline, outside air temp was 60f, not running the alcohol injection , egt was in the 1400-1450 range. mods are in profile , 14 psi on s16g. thanx, i might have a minor boost leak as well i gotta test her.

The boost leak and/also maybe an exhaust leak is evident from the low O2 readings. Fix that first before you start trying to tune. Then do another pull.

Also only log the crucial things. Monitor your L M H fuel trims every now and then. No need to log them as they only update every once in a while. Log timing, o2, rpm, knock, injector duty, tps. You are running lean, but suprisingly no knock. Timing looks good too. Check out your manifold to head, manifold to turbo, turbo to o2 housing for leaks.

The reason it "appears" that he is running lean is because of leaks, and probably around the area you speak of...exhaust. In all actuallity he is probably running super rich and that is the reason he has virtually no knock.

ok thanks guys im gonna boost leak test , and check for exhaust leaks
