Just got back from REVO HQ.
The correct software has been loaded on and set to B6 T4 F9, it pulls very very well. I also managed to come away with the DSG remap software too....
The noise on full boost has been confirmed as wastegate regulating boost pressure (just as PDT thought). I may have a problem with the seals on the fuel pump (slight smell of fuel in the oil) even though Carl logged the rail pressure and said it measured what he expected from an OEM pump. So ill get the oil changed asap and keep and eye on it to see if it is been contaminated, if it is then its a new pump
, its only done 36000 miles....
