Thanks I got it figured out. I originally posted this thread in 2019. It was an ECU issue

Yes I finally got it worked out. My ECU was not seeing the tire size and I could not change the parameters in the transmission. I got a new to me ECU (used) and loaded it up. Had it tuned at a shop. Also my Diablo tuner needed an update and may have been the whole issue. Went to Big Bend went...

Love your car by the way. You have helped me out tremendously over the years.

Yes there are 2 straights. Maybe there is a limiter on there I have not done a custom tune only have a Diablo tune on it. Did not think of that being the problem. Will have to find some place to go to test. The COTO track is too expensive for me I got lucky and got in after someone dropped out...

That’s what I figured I wasn’t sure if I changed from a 373 to a different gear it would help
