I have a Star Kit w/ starion I/C and everytime I'm at say 1/2 throttle cruising at 3k then I push it 3/4 to almost full I get a hesitation and the A/F goes lean until i reach 4.5 then goes rich. I've checked my plugs, wires and have done the fuel pump mod but still can't figure it out. I remember I think Stan said that is the nature of a FPR cuz at 0lbs there is a flat spot. Is there any way to cure this? thanks

doesnt matter what your air/fuel says unless your flooring it. Also, its completely normal for a/f to go lean, then rich when you floor it.

Mechanically speaking how does that Vortech FPR work?...thanks
