A little summary:
Turbo is from Audi TTS (K04-064)
Exhaust system is 76mm all the way with Milltek backbox.
Car is very quiet and I am very satisfied, almost like stock, however it has nice sound under hard acceleration.
At the moment I am driving with the small MAF and the small injectors, because I have to sort out the clutch before going on dyno.
Anyway with stock injectors and MAF I am reading 203 g/s around 5800 rpm, and then the car gets MAF signal too high and Charge Pressure Maximum Limit Exceeded. I suppose that this is the limit of the small MAF.
I have 630cc Genesis injectors and S3 MAF ready to install and I hope I will get another 40-50 g/s when car is ready.
