Guys,

as it says in the title im getting a boost problem when only on wide open throttle, i can hear the turbo spinning up but when i get to roughly 3000rpm it just dies, well more like a sudden loss of power, I have changed out the WGFV and the DV but this makes no difference......

I also tried disconnecting the WGFV and just give it mechanical boost but still the same

Could it be the MAF or Plugs, fuel pump??? or anything else i'm missing?

Car runs fine when not driven on boost

Thanks in advanced, and it's the S2 not RS2
