Yes, when we did the tire size and gear correction we also put a trans tune on it but didnt change engine settings. 1 guy on the FB page did it that way and i wanted to try it that way tooSSpeedracer wrote: ↑Thu May 27, 2021 9:25 pm Have you tuned/programmed the transmission shift points etc?

I trap at 105 and in 4th thats like 4400 rpm lol stock dyno sheets look flat from 4.2-5k anyway. I primarily race 1/8, im at 4500 at the end there too so it just sucks. ...
