Me and a friend were test driving the car tonite. Anyway, when we were at about 110 mph, the speed-o-meter needle jumped down to 80 then back to 110 real quick. The car did seem to cut out a little but we did not slow alot. I stayed in it, and it kept cutting out. We stopped and turned around, and tried again. The car did the same thing, but still kept pulling till about 120. Then it did the little cut-out thing and the neddle jumped again, to about 80 then back up to 120. The little cut-out thing dosent feel like a big miss, or anything bad. Just feels like the car is "fighting" the speed of going that fast. Is this the "speed limiter"? I thought I had that programmed out when the guy did the chip. Also, is'nt my cars speed-o-meter driven by a gear? (93) Could this be slipping? Thnx
