first time at the track...still not perfect hello there.
I went to the track and got to run the car out a few times and learned how it would behave. I found out that the tranny was not shifting down the track and it would go and lock the converter...then I tried to do a pass with me shifting the tranny manually and got better results but not great. I am running very rich and the tranny tune is not correct. seems like the shift points are not set right and the values need to be changed. I just intalled the 4l80E on the 98 formula and used a 4l60E file just tweeked a little to make it work in the street.
here are my results
RT .838
60' 1.695
1/8 8.026
MPH 88.97
1/4 12.356
MPH 114.78
another pass
RT 1.087
60' 1.88
1/8 7.9
MPH 92.31
1/4 12.20
MPH 116.6
the car should run better after a good tune. I am running the car with full interior and just like I drive it in the streets. only thing I do at the track is lower the PSI to 15 lbs.
I am torn on where to take the car down here. I have taken this car to so many people (reputable shops) and get nothing but crappy tunes.

No I haven't tried them, I live down south and it would be a long drive, but I am looking at options right now. The last time I had it tunned was in DFW area, the tune right now is super rich and not good at all in other aspects according to some one else that took a look at the tune.

Dont Worry Man I got you Covered. I will do everything I can to get your car to run the way it should....
As long as all the bugs are worked out in the wiring of the 4l80 and its just in the tune I know for sure I can get the car to preform. If there is some bugs we will figure them out.
