Qmp kit overboosting? Hey guys got the qmp kit installed and what not. When the car sees around 3500rpms the car immediatly sees over 20lbs of boost, the gauge I have maxes out. It does not drop either. We checked the wastegate and found that the valve was stuck. We used a hammer and fixed that to where it was fluidly moving. I have the 10lb spring in there also. Took the car out again and the same thing. I have an hKS EVC5, no matter which setting as far as lbs go its on the car still sees 20lbs. The evc5 was installed exactly the way the instructions said. Could it be that the wastegate is bad or could it be that the Evc is wired up incorrectly? Any help is appreciated!
Whoa!....20psi on the stock bottom end ehh. it must pull like a *****, Good luck on the solution, I know these guys will help you. have you called qmp and talked with Rob about it.

make sure the WG is hooked up correctly to the vaccum source and the vaccum source is correct.

As in one line runs to the wastegate splits and goes to the bottom of the wastegate, and the other part goest to the turbo. Another line goes to the side of the wastegate. Then we have another split line going to right behind the tb and to the bov. IS this all FUBARD?

do a search on Mightymouse on this and ls1.com site . he had a similar issue with over boost. if my memory serves me correctly the extreem over boosts caused massive back pressue problems and i "think" he either cracked the welds on the log or he ended up with some valve train problems.... dont hold me to that but do a search on him or pm/email him ,Dave is a very helpful and nice guy.
run a vacuum line from the manifold or turbo (i prefer manifold as that is engine boost) directly to the wastegate. take the boost controller totally out of the equation for right now.
and yes, is it a manual or electric boost guage??
you got my # call if you need help or anything

If you connect it this way and still see 20 pounds, then it's a controller problem.
Hope that helps.

if it goes to (and holds) 20psi... and motor still runs.. LEAVE IT! and get to a dyno/track
also make sure your p.e. table is like 2:1 lol
i told you to skip the controller last night
leave the bov alone

You need to control the boost at the intake. It's not important what the boost is at the turbo because that doesn't take into account the losses from the pipes and I/C.
