    heyhey
    i have a KO4 AEB & some other mods. i was only boosting with 15psi for sometime and have been search for boost leaks & testing other things. i swapped in the N75f and it boosted great!!! I think this is the 1st time i felt the KO4. but it only lasted 4-5 days and now i cant boost past 5psi.
    i put back in the N75C and it boost back to 15psi again. can i use a MBC and set the boost to reduce pressure & spikes of the N75F so it does not throw me into limp mode etc.
    I know i can bypass the N75 altogether but i already bought it and would still like to use it if needed :)
    i was looking at this:

    My vote is to bypass the N75 all-together and use the money you get from ditching the N75 to purchase the MBC.

    The downside to ditching the N75 on the small K03 or K04 is you would then have a throttle that's an On/Off switch.... You'd lose all of your part-throttle modulation from what I've read and heard.
