I definitely have boost 😁 but its worth checking it anyway for sure. And yes maf is giving good readings I am also a bit confused with it all now myself. I am going to definitely recheck the turbo actuator and check underneath for boost pipe leaks next

As far as I know its a single turbo
And it was a Quinton hazell one, I havent had any problems with their stuff before and it seemed good quality when it went in so I'm guessing its OK. |

I dont think the engine mounts make any difference on ours for boost but they are vaccume operated. They go hard or soft up to 1500 rpm cant remember which way round. Dont think that would cause your issue but maybe check them. Is your intercooler ok

Yeah they are supposed to be hard until 1500 i think, but yeah I will check them also that is a good idea. I have smoke tested intercooler and couldn't find an issue unless its blowing open under pressure maybe

Haha like your thinking but I have already tried that one 😅
And I believe so yes. I think when I checked soot levels it said 6 which I think is acceptable |

Probably not near henlade though!! Fuel trim levels? Maybe do a live read to replicate stutter etc see what its asking to actual.

Wouldn't know how to smoke test the plumbing to reach a conclusion that there are no leaks. Wonder what the cost of the flexible pipework is.

I would try some contact lubricant on the injector connectors.
I use ACF50 for this, which is great stuff, but others might suit. https://www.ebay.co.uk/itm/ACF-50-Mo...YAAOSwQsNZ0i4x Although ACF50 is not cheap, an aerosol can lasts me years ! Issues with injector connectors are not unusual for causing misfire fault codes.
