My problem was with the goodyear tires on my '91 TT I either burned out too much or bogged during take off. This is with a Stillen Intake and Greddy exhaust. You can see how bad the 60' time was. Couldn't find that middle point with the 5 speed. How did you get such a great 60' time? Is that an automatic? My other car, an '85 Corvette automatic, get's a 1.9 60' time @13.66 1/4 mile. Here's my 91' TT times.. : 60' 2.347 : 330 6.044 : 1/8 9.10 : 1/4 13.936 : MPH 101.33
