i think i am having the same issue with my aum turbo had ot remapped and fitted a boost gague was peaking about 18-19psi and holding around 17psi, now 18months later (only done 7-8k miles since remap) the boost is down to 16-17psi at peak and hold at around 15psi.

N75 at fault? would getting a ECS race n75 value be nessacary with a remap?

ive got a brand new n75 which helped as it would not even peak at 21psi as it should with old one, but them race valve of which you speak are just a rip off as its just a h valve from a 2.7 twin turbo audi iirc, with a sticker on them and they charge 20 + quid more. mine got mapped on the standard valve (C) and was fine and now i have (F) which replace (C) valve at vw.

i got a funny feeling, mine has been having simular issues and i have a feeling its down to a dodgy pcv valve. could i be barking up the wrong tree? as i was just thinking if it was stuck open then some of the boost would leak back to the TIP and i think thats the issue i am seeing. im going to replace it next week and see how it goes.

where can i get a F valve from? audi s3? or tt? mk5? and how much did yours cost you around £50?
