Right finally had time to take it out for a quick spin.
It was all going daisy like, started first turn of the key, idling like normal, wasn't boosting because it hadn't warmed up. Once it did I gave it a nudge, wouldn't go past 3500rpm, stalled while in second, lotsa stalling when creeping round in first and the snakes back
Looked at the BOV couldn't see any fluids but then again I'm fairly new to cars spec scoobs so I might be missing it
Taking it to a garage on friday because I don't have time to Q/A it myself..
