    DumpValve install??

    How have you guys installed yours?
    Boost in the side, and vent out the bottom?
    or viceversa?

    Have just installed mine according to the instructions, but i think it´s acting strange

    The correct orientation is the control port pointed towards the chassis leg...

          The old DV was leaking A LOT, so it gets quicker boost, more boost in some rpm(between 3k-5k rpm) and it holds the boost as it should, not fluctuate all over the place.
          It had to "learn" the new boost curve (i think at least)
          After 5-6 full throttle 2-3-4gear acc it was spot on
