iv just plugged it in to vag com, and maf is fluttering between 20 and 50 right up through the rev range. and thats a long way off where it should be. only got vag com today and i havent registered it so i cant check actual vs requested boost which is gay but cant afford the 100 quid to register at the mo. any way the maf is new about a month ago, which rules out a knackerd maf, so mabye boost leak, knackerd dv, n75,etc etc, any help from u tech guys much appreciated as im not the most clued up person on this. thanks
