So i just installed a buschur racing ported tb and intake manifold, first the one i recieved was alittle different than the one on my car, such as different vacuum ports also the map sensor provision was not drilled out like on the stock one of mine but that was a quick easy fix. The problem i have is every since i put them on, when i dive the car and hit about 22-25 psi and go to shift the the rpms continue to rise as if im not letting off the gas pedal, it sorta seems like the blw off valve is not releasing all the presure in the system anyone have a clue what could cause this.

 

Maybe the butterfly on the tb is getting held open go over the install again
