    56MM THROTTLE

    Has anybody seen any real rpm or power gain in swaping the 52mm throttle to the 56mm???. and how does the ecu ajust for the extra air coming in because it has a map sensor and not a maf sensor?????

    Im running one
    I did it all at the same time so i couldn't tell if it was that or everything else.
    but i can say that with the rr ecu and external ic, the F/A ratio is in the high 12 at WOT. 12.8 mostly
    and my boat accelerates So hard now, its scary.
