    10-04-2012 04:59 PM #1
    Guys Guys chill...

    Im saying the problem should be the N75 Valve not working correctly... ill get a borrowed N75 to check if it is solved... if it is i may be up for the Race N75 ECS offers

    Dude.. Start your own thread. What your doing is the equivelant of walking up to a conversation, interrupting, them starting your own. Derailing the topic is not cool.

    a new oem n75 should not go bad in 3 months... how old was the one that died?

    3 days ago... out of nowhere it just spooled up slower and reached 6 psi below my normal levels

    Normally she puts 24psi and holds 16 at redline... now barely hits 18 and barely holds 9 at redline

    Sounds like you're having a wastegate actuator issue. Check the nuts and rod you may have to adjust the nuts a little

    Seriously though, check them.

    Yes, the nut could be loose.

    if they aren't try tightening them down a little (cranking it) a couple threads and see how she reacts. If the actuator is on its way out you may have to crank it dow every once in a while until you run out of threads... then need a new actuator, or turbo for the price.
