Audi will sell you the n75j valve and if you have a Baileys unit it needs to be a twin piston type or it will not work right and Audi's are recirulating as stock.

The N75j is from the RS2 I think hence why you can buy it from Audi it's a Audi part at the end of the day.

ok found it n75j part nO 034.906.283J £48.97 inc vat is that a good price?? and what psi would my turbo run at stock because after remap im only at JUST 10psi ive heard after remap should be looking at 12/13 psi

A remap should se around 14-15psi the n75j just holds the boost better and piles it on stronger but you soon forget about it.

and ive heard some people bypass n75j valve is this a wise move??

Check you don't have any leaks, then check the waste gate is opening and did you change the DV when you was remaped as they tend to go shortly after so upgrade to the 225 TT unit or after market as this will effect boost, thinking about it check the DV first.

my dump valve is working you can hear it whooshing releasing boost i will inspect now....if it stops raining
