    boost fluctuation. off to amd thursday. what do u tink it is??? place your bets now!!

    well basically i still have this boost fluctuation at low revs on partial throttle. have had a n259 bypass done. and re newed the n75 valve for a genuine audi one. and also got rid of the nasty split-r valve and put a new oo7p on ther with the correct spring. but still the boost issue is here have had a stage 1 remap at amd in woking. and to be fair it has been doing it ever since

    i am going to amd "ESSEX" thursday to have it data logged and to once and for all find this problem e.t.c im pretty confident they will find it.

    be interesting to see what you guys think. and i will post up when i get back to let you no what happens.

    i think its the remap.

    any other thoughts???

    I had boost spike with DV hose leak (jubilee clip had sheared a pipe).

    Also there are a range of N75 valves, and I'm not sure they are all interchangeable, so you may want to check with AmD that the one you have is compatible.

    Also may be worth having the waste gate actuator checked.
