Got my car tuned up this weekend after having it apart for some time installing lots of goodies. At the transition (between primary and secondary turbo) my car was stuttering a lot and you could hear the blowoff valve venting in short bursts. Meanwhile the boost guage was really jumpy. What could this be? a hose could have blown off I guess? I thought I should be more at 13psi not 11 since I am runing dp, mp, apexi cb, open intake, m2 intercooler, 1300cc secondaries, pulleys, pfc. I found a broken silinod that runs to the ypipe off the pressure box - little black box in front of the UIM. Could that be it?

Any help is greatly appreciated!

 

That could definitely be it. If it is not it is definitely a good starting point.

 

Thanks! Any other ideas? I guess I could pull the UIM off again and make sure all the hoses are connected. Dang, wish I had the money to go single and get rid of these stupid little problems

Thanks again!
