Hi all, new to the group and after some much needed help, my car is barely boosting, at 1st it was intermittent now it's full time, at around 2.5k revs you can hear air hissing out and there's practically no boost, there's no leaks as its all been checked, actuator is fine waste gate is fine and turbo is good! When you take the hose off the before the dump valve the car goes nuts! It's a ridiculous amount of boost but put the pipe back on an nothing again,no faults come up on the reader, it's had throttle pedal change, n75 valve, new dump valve, a bit stuck now? Anybody else had this issue before?? Please help!
