I've also been told that the issue could be an injector going bad. Using the AE scan tool I have no codes and it passes cylinder contribution test and injector buzz test.

if one injector is not firing will it be noticeable because it idles pretty smooth now but still can fill a slight vibration at idle and while moving. also when i start it in the morning if fill the exhaust manifold with my hand while its still cold and at idle and they all seem to be the same temp as each other, so i think they all are firing. My egts are still high, at idle its 400*, driving empty at 60 mph its 900*.

I also have this same issue with my e99. I've replaced the ICP sensor, IPR, (new) original black CPS, Throttle pedal with all new sensors, and performed the Hutch mod and added the AirDog. None of this has made a dent in the miss or stutter that I experience. I haven't done the 50 cent mod or even checked my UVH yet.

I've heard good things about the PMT1 and 2, plan on doing that upgrade anyhow to smooth out my motor but I wonder if the E99's have a PCM that causes the engine to not run nicely.
