I performed all of this last Thursday and I immediately noticed a huge improvement in the startup and idle. One of my main issues before was a horrible stuttering under any type of acceleration and steady cruising. I was also throwing misfire codes constantly but now most of these issues are resolved.

There is still a hesitation whenever I accelerate with more than 1/2 to 2/3 throttle and the only resolve is to back off the pedal slightly. I also managed to throw another misfire code today while I was thrashing the car a bit to see how it behaved. Now I know.
No lapping for me yet!!
And of course, it feels down on power. There's no way it's making anywhere close to 440whp.
I e-mailed Stillen a couple of times to tell them the issues that I'm still experiencing and asked what my options are and what was being done to resolve the ongoing issues. My response was that "he'll forward it to the guys in the shop"

Will Stillen come to Canada to pick up my car as well?
