About 400nm torque I have lost. Boost will pick up around 4000 now . It use to pick up at 2800. Blow valve has been disconnected hoping it was the issue, idol is now rough, and will stall here and there, wastegate seems fine. Checked piping seems to look fine. Need to make up some ends up so I can pressure the cooler and intercooler pipes to prove its fine. Tommorow I'm disconnecting the waste gate actuator line so it will just keep boosting. And probably pull the wastgate apart to see if. If it's craped it self. The wastegate is only 8000kms old. Got any suggestions I'm also thinking might have skipped a tooth because of idol now playing up Link to comment https://www.fordxr6turbo.com/forum/topic/88211-down-5-psi-down-low-mid-range/ Share on other sites More sharing options...

If not you might have created a vacuum leak. If it did you still might have a vacuum leak of some sort, which would be an air leak post throttle body and covers all vacuum hoses, so check if any blew off or are cracked/perished. If its just taking a long time to spool look for a charge pipe leak, ie from turbo outlet to throttle body - quite often its a silicone hose half dislodged, or a crack in the intercooler if you bumped it in a car park or something like that.
