I did notice that the idle was doing something weird. While at idle it go up and down up and down. Once I found the sweet spot it still did it however when racing it ran great. What should I do to get that awesome run time again without having to go so lean.
Are you sure your temp gun was reading right? My OD temp gun has been reading 60deg higher and I didn't even know. So I have been running everything very rich. I was pitting at 8min with the B5 and knew that was short but the temp was reading 260deg. Turns out the motor was only around 200deg when temped with a real gun. Just goes to show we put to much trust in them temp guns.
