03 N|a mach 1 air\fuel ratio
I have a buddy with a 03 Mach 1 mustang with a built motor, He has a SCT but his car does not idle good when it warms up, I let him use my wideband and when he starts his car when it is cold it runs 13.5 then as it warms up it goes all the way to 18 -19 at idle and wants to die. At wot it runs 12.5. His tuner says that it is normal. What you all think?

what do you mean "built"? and i'll take a shot in the dark and say no, that's not wholly normal.

well... 12.8a/f at wot is perfect for N/A. After my dyno tune i was around 13.1-13.2 but thats for a little more power. 12.5 is little bit rich which is fine. not too sure on the idle part tho. i
