What tranny are you using?

Reason I ask is because I have a 60E (It has the vacuum modulator vs. the 65E electric one). It was doing exactly what yours was doing because the vacuum line slipped off the modulator. Popped it back on and it's been fine ever since. The weird part is the vacuum leak never affected my idle or anything.

They spoke with me earlier in the day and showed much interest in the Fiero. They also were aware I was shooting for 11's that's why at the end they got excited, oh oh oh lol I ran a 12.009 can't get much closer to 11 then that.

Made some adjustments to the tune on the dyno. The quest for 11's continue....

Ran it at the track with street tires because the wheels and slicks I bought won't fit over the new brakes I couldn't get the 1.6 60' I usaully get because I broke traction every time, the best I pulled off was a 1.75 60' 11.6 at 119mph not too bad... Ordered drag radials today, I'm sure that number will be getting lower in the very near future.

^^^ Me too ^^^

Street tires breaking right thru the 60' but still not a bad run. Left lane #5333
