What elekie doctor said. It could be as simple as a clamp not done up properly.

Hi guys, thanks for the replies so far. At first I thought it might be something to do with the boost solenoid so checked it was piped up correctly from checking pictures of the same engine on the web.

I also checked the solenoid could hold a vacuum with a brake bleeder tool and that it works when connected directly to the battery. I'm planning to take it back to another garage as I also think it could be a problem with turbo hosing damaged or not connected properly.

The thing I'm mostly concerned about now is how the engine will rev up cleanly when I am sitting in neutral and with the clutch in, but when I put it in gear and hold the clutch in, it doesn't want to rev up (hesitates/feels like its being held back). I thought if the clutch was in, the engine would be completely disconnected from the gearbox so it wouldn't matter if it was in gear or not (and affect revving).

I thought this might be a sign of a incorrectly fitted clutch? If this was the case then I would take it back to the place who fitted it.

Also I'm not sure if this could be related to the boost leak or a separate issue.
