[A4 TURBO]

i cant seem to find a n75j valve where can i get one?? and does anyone know what my best option is for dump valve i have NO IDEA if this baileys one ive found is right is audis blow off or recirulate??

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

Any One Please??????

Any One Please??????

Did you check fo leaks and make sure that all the clamps are on tight if that fails then one will have to say you have a crap map or your waste gate may be faulty but VAGCOM it if you can to see if you have any codes.

Checked all pipes they fine........ ive come to conclusion the remapped chip is just a generic super chip all it has doen is increase fuel etc. to prove this hardly any difference in psi increase between stock chip and upgraded chip the only difference i have noticed is fuel economy. for example £10.00 of petrol got me 40 miles!!!! it was never that bad untill i upgraded chip. so im going to save and get the PROPER remap done professonally which is what i should of sone in first place. iim gett n75j valve soon so that should help.Im going to miss that extra power the superchip gave but its just caused to many problems and fuel was poo!!!!!!!! i had the simlar problem on last car nissan when super chip on the car it picked up better and fuel mpg went dowwwwwwwnnnnnnnnnn .

manual boost controller might be worth while some people say they work fine while others dont got mixed opinions
