I have a stage 2 remap with a Ko3s turbo and an upgrade large FMIC, I dnt think my MAF is getting enough air into the engine can some point me in the right direction? I have heard an 99 RS4 MAF is a straight swap and will get enough air through the engine

what engine code? I have a stage 2 AGU with the same as you and it's fine. The later MAFs can see more air so that won't be a prob either

The code is AUG I was told it maybe the MAF coz when boosting it starts to lose power higher in the revs, but sometimes it's like the boost doesn't even kick in?

You need to have a look for fault codes, also do some MAF logs
