Hello everyone.
I have a 3000gt with a recently rebuilt engine.
She runs great and pulls good for only 7psi on the 19ts.
Even though she is on the stock tune, she runs lean at idle and when cruising according to the wideband. She will idle around 17 and even dip to 22.5. During cruise shes from 14-16.5. What should a stock tune run as far as afr.
During load or wot she runs great pulls hard and has an afr in the 10s-11.
THe car has 30 over pistons, could that be the issue?
I have checked for boost leaks and she holds steady.
How much boost could I push on stock fuel before I tune her on the 19ts.
Also she has a bit of a hesistation when at wot. Could this be tied in? Im not sure if its the car actually running that lean or if the wideband is screwy. She doesn't act like she is lean and she has a very steady idle around 670-700 rpm.
Thanks for your time.
