My problem is when I have about 2lbs boost when I'm just giving it a little gad to go up a grade or hill without really getting into the supercharger all the way.When it starts bucking a little I let off a lttle or give it alot ofgas and it goes away.It kinda reminds me of driving my Goat with Tri-Power. your either running 2bbl or your running 3-2bbls wide open, don't play around in the middle.I asked this question on here when I joined and everybody told me it was my wires/plugs. Changed all that and it'* still doing it over 2 years later. I just live with it or give it more than 2lbs boost.
