I have a Whipple car with built 10 speed/ circle d converter. The past few times I’ve been out racing I’ve noticed on the 3-4 it’ll shift at 7300 then drop to 5600-5700 and almost feel kinda lugged down. In the past it never seemed to drop below 6400 or so. Every other gear shifts at 7800 and stays higher in the rpm band. The tuner mentioned it could be something with TC since it usually spins some when I punch it in 3rd and will slightly spin on the shift as well. I have advancetrak off and it doesn’t seem to be cutting fuel/spark based on the logs. Just curious if anyone else has experienced this.
