Another fairly big update.
Was losing boost quite substantially in the higher rev range, and peak power was 230bhp
Big thanks to PDT for spending time on my car narrowing down where the issue could be and er...turning my exhaust round the correct way.
I had a smoke test done, which showed boost pipes were fine.
Took the car to PSI tuning in stoke to have the DP taken off and the turbo inspected for a crack. They have taken the intake off and blanked off the DV in search of a loud screech that comes from the car when on boost. Its pointing to the turbo, it could be something as cheap as a gasket or as expensive as the turbo internals, but didnt want to say 100% unless the turbo is off the car.
I have decided to go K04 rather than spending cash taking a turbo off and replacing it with the same thing. PSI has made me an offer i cant refuse regarding going to APR software + Fitting turbo. Two benefits i can see are that it doesn't disappear when disconnecting the battery and i can once again return to Awesome GTI for any map changes.
I never really planned to go K04 when i got the car and has been a hard decision to make as to if its going to be worth it, but with 310-330bhp its means i have a much bigger willy to wave now.
PSI tuning offer APR and CC remaps, APR don't do a DSG map and from what i have read i wouldn't touch a CC map. So i will be hopefully taking the car to Nick @ R tech for his DSG map.
