i installed a greddy front mount kit and 3 inch downpipe and the car is boosting 25 and hitting fuel cut real bad , the kit had the pipes with it too and the pipe that comes off the turbo had a line from the wastegate and the new pipe didnt have no place to hook up the hose from the waste gate. i have tried a man boost controller and it still boost 25 and hits fuel cut please i dont now why it keeps hiting 25 in stead of factory settings if the factory solinod is still hook up?

 

if you didn't hook up the line that used to be on the lower intercooler pipe, the the boost control solenoid isn't getting a pressure reading and cannot control boost properly. You can tee this line of the hose the connects to the bov, that should fix your problem. If not, then it has to be a tuning issue. Could be running too lean. Try the first thing, and if that doesn't work, take it somewhere for some tests.

 

thanks but the waste gate line should be hook to the blow off vavle

 

You can hook up the line that was hooked to the nipple on the stock turbo pipe to the blow off valve vaccum line. Just T into the BOV line and that will work for a pressure source for the stock boost solenoid. There is a diagram in the Greddy directions on the last page, I think that shows this. It is kind of hard to follow, but that is the way that it is supposed to be hooked up. You are running with no boost control at all, that is why the boost is going to 25 psi and hitting boost cut. Get this fixed immediately if you haven't already.

Are you in Taylorsville NC?
