When I looked at the car after updating the ECU there were no recorded misfires on the live data, and no faults flagged.

The ECU was updated to get rid of a couple of usual faults caused by the original tune, the MGR updated tune gets rid of them. The car had not been PDI'd and no market selected which is quite usual for cars sold by the administrators after MGR went bust.

The only thing we could find on the live data was that the boost was intermittently too high. This coincided with the poor running of the engine.
Tim has fitted a new boost control solenoid but the symptoms have continued.

The only other thing that I can think of at the moment is that it might be the MAP sensor. I haven't got a Turbo one for him to try what would be useful is to be able to try one to see if it improves things.
Is there anyone with a 18T nearby who is willing to help?
