Your #'s are pretty good. I just put down 283rwhp and 319rwtq with my mods in my sig but my car was running very rich. I was in the low 11's to mid 10's on my a/f. The higher the rpm the richer it got. I need to get my car tuned badly.

His cruise numbers seem a bit lean, but the WOT number seems about right...13.0 is about where you want to be...at least thats what I've always been told...

Every car is different on a/f but I'd say that 12.5 is a bit rich as well. I'd say 13.2 - 13.0 with it dipping to 12.8 at peak torque would be the best to shoot for, but I wouldn't complain how it is, especially if that is untuned. Excellent numbers too, not sure if anyone noticed, but the car is an A4.
