been lookinh on vw and audi forums and those guys seem to be changing the pressure regulator valves on they're cars, has anyone here done this and if so have ther encountered any problems??

they seem to think that the J variant works well on older agm engines with the throttle cable but not too well on the newer aum, drive by wire engines

any help on this would be blooming marvelous as for about

I ran an N75J for a little while and it does give a little more boost...around 0.1 bar. It does however hit the overboost limiter rather quickly, well it did on mine, so you can hear the turbo pulsing.

Only put it on to see if it would cure my low rev tardiness. Did to a certain extent but not a good as it is now.

Also had the map tweaked with the N75J in place......ended up being very rough so was a no go.

You have to becareful which N75 variant you use as it may put the engine into limp mode due to too much boost....I think the Seat guys are using H versions (can't remember of this is the race one or it tha tthe K :confused: ).

You can get the N75J from vagparts.com and it is

I have tried the N75J and the N75H (the stock on mine is the F version)

Both give higher overboost pressure (the H much more) and hold the pressure high enough at high revs. Impressive is the torque you gain with the J valve in the mid revs.

But I was hitting limp mode with both J and H, so I bought the overboost solution kit from www.boostvalve.com. This cured the overboost problem, but then I was hitting limp mode at mid revs when trying to accelerate (not in WOT).

It all depends on the program you run. Other guys here with revo or abt chip for the rs, do not face any problem. It's a matter of where the pressure limiter is and the discrepancy between requested versus achieved (or better trying to achieve) pressure.
