[QUOTE="DontGetBit, post: 3622961, member: 21960"] I am having trouble with my car hesitating while under boost. It does not feel very smooth and once I lift the throttle it feels like the engine is missing. The sound of the changes for a few seconds after a WOT run and the car sputters. I recently had a plug blow out of the head. I had a Timesert installed, changed all plugs (gapped to .032), and installed a new coil. I just took the car out to log the a/f with my WBC and everything looks great. The a/f drops to 12.0 at ~2500rpm and stays around 11.6-12.0 until I lift the throttle. I was uncomfortable running the car over 4500rpm due to the hesitation. Any ideas of what the problem may be? I can post the data log from the WBC and Predator if that would help diagnose or rule out any problems. [/QUOTE]
