I’ve been having issues with boost. Done multiple smoke and boost leak test and found multiple leaks that have been solved. Changed diverter valve first still no boost, then went on to change turbo which had some play but oil feed line and return line were very clogged up. Car was picking up nice up to 2.5k revs and I wasn’t pushing it for 300 miles to break in the turbo. Even after the change the car still has no boost it feels. I had code P0441 and P0332. I’ve replaced the knock sensor and evap system and no codes are active or have come up since. Changed the evap system too with n80 valve and Vapor canister with hose. Yet the car still has nothing past 3k revs. It feels very flat no torque pushing you back. The timing chain timing belt have been done. The engine idles completely fine and isn’t acting strange right now at least. It takes about 1min 27 from cold to steady up at 740-780rpm. Had balance shaft delete. I’m just so lost I don’t know why it’s so poor. I’ve just been throwing loads of money at it with no progress. Any help appreciated.
