  • Strange Problem

    Whenever I redline in 4th and at the switch to 5th my PSI drops hardcore to 10 and will either hit soft limp or slowly creep back up to my regular PSI. This only happens on my 4th to 5th gear change. 1-4 are perfect. Anyone every experience this?

    ECU is pulling boost or opening the DV... not much you can do, Diode might work.

      Damn it,

      Hmmmm it happens with a MBC or without. N75F or J valve. I was testing last night the MBC with the n75F valve and it seems to be a little better. I dont get as crazy spikes .... hold at 18 is very nice. I was thinking the J would spike me to 20 and the ECU freaked out and pulled timing. Well its time for DIODE. Hey Kor whatcha doing tonight?

        Not connecting a diode in your car Unfortunately yesterday was my mod day, today I am working. Since I just got up at noon, I am guessing I will be working late.
