Hello,
I have a 99 GT mustang with the following mods:
Stage 1 heads & cams
Cold air intake
Aluminum drive shaft
BBK “3 inch” o/r mid pipe
BBK shorty headers
Magnaflow Catback “3 inch”
BBK underdrive pulleys
70mm throttle body
75mm plenum
The car was running great but recently and after the install of the stage 1 heads and cams the idle is not really stable anymore. When the car is cold the idle is all over the place (up & down), when the car gets warm, it idles fine. The car also stalls sometimes especially when I hit the clutch while slowing down or getting into a turn. I didn’t tune the car yet, but as far as I know stage 1 cams and heads don’t need to be tuned. But I could be wrong. Anyways, I have a Diablo hand held tuner, so what do you guys suggest? Mail order tune?
Thanks
