Help please! V7 STI

I've got a version 8 STI solenoid for sale if you needed one cheap.

I'd say it's been running in limp mode to try save itself from grenading. That's generally what happens with these guys who can't figure out a simple CEL issue, then try to bypass it to force boost when in reality it's probably detonating or something and the ecu is picking up knock and adjusting everything to save itself from permanent damage.

 

Boon's advice is accurate. Putting a manual boost controller on a car that isn't running right is moronic so please don't act like his opinion is rude, you are being rude by asking for help then rubbishing the advice given.

 

You've been given a bunch of potential issues to investigate now get to it

Hey all orrt if i rubbed people up the wrong way, and sorry for my bad way of explaining things. I have trouble with wording things appropriately when explaining them.

 

Anyhow i got the issues sorted figured out my fuel pressure was miles high (65psi) and weirdly wouldnt run unless it was above 50 and wouldn’t actually rev or have half decent throttle response unless it was over 75psi. I had installed a Sard fuel pressure regulator and then turned to another stock ecu which once installed and the fuel pressure lowered made the car almost perfect! Im thinking the original ecu had been reflashed as the fuel pump was flowing to much for the stock regulator to bypass. Still not running 100% perfect but im sure its because of the blow off valve. Anyways thanks for all the input guys been a long time chasing this issue!
