Running Rich.
#11
UPDATE: I have replaced Water Thermosensor which didn't show ohms according to the manual. That little thing costs 30 bucks at auto zone. Anyway, Idles better, It doesn't run as rich, however stupid hesitation or whatever you call it is still there.
I also notice that when it happens, on my PFS keypad, on the o2 sensor reading it shows 0 when that occurs. As if there is no fuel, like a fuel cut. IT's really anoying as it's trying to pull but then it won't and then it will. I was runing 7psi and no hesitation, 8 psi spike and it happens. I know 7psi is stock safety boost, what else could it be. I just wasted 30 bucks

Well, I did that not too long ago, hesitation was still there. Then after like 5-10 minutes check engine light came on with the feedback crap and it was even worse.
Also, I Checked Fuel pump pressure. When GND and F/P are shorted i get 38psi. When Idling i get 32.
Also, for some reason I can't raise boost at all. If i use low or high boost and turn it up on profec B, no difference. I only get 7psi and when it spikes to 8 that's when bucking and crap occurs.

Anybody else has any input on this problem? It would be wortheless for me to change twins, if i get the same problem.
Why is this bucking and hesitation and what not keeping the profec from raising boost?
Someone please help.
