    F.A.S.T Throttle Body 92MM

    Hey Guys!

    Hope this isnt a repetitive question. My tuner had major concerns and cripes about the FAST throttle body... He tried for hours to get it to idle without dying all the time!!.. He even drilled a pin size hole in the plate itself...

    To make a long story short he did insist I go with the NW in lieu of the FAST,,, the one and only advise I didnt use... I dont want to go thru another season with this thing not wanting to idle at start up.. Im looking for a replacement TB now.. Will I need the tune touched up after the swap or will it correct itself?? (is Nick Williams the way to go??)

    I have the Ported FAST intake and Throttle Body now with Fully ported and Polished Heads.. 320 @ 600 lift...

    any help would be appreciated..
