Well i still have my hesitation and poping out the exhaust which i still cant figure out. It happens very frequentley under half throttle, if you mash the throttle she wakes up and acts normal. Any ideas on that would be awesome. Also i was checking fuel pressure and saw that under just 4lbs of boost the gauge sky rocketed to 80psi! I do have the vortech FMU but not sure of the ratio. Whatever it is i know it souldnt be that. What could cause that as well? And it also does not hold fuel pressure after priming which cause starts to drop low because the lack of fuel pressure in the rail. Confused. Any info greatly appreciated. Been too busy to pull codes. Will try soon though.

If i do ditch the FMU, What all should i do? I just got a BBK fuel regulator and they are not boost reference. And i do not have a timing retard hooked up at this time.
