I bracket race this car and every so often I get strange issues pop up like this one yesterday. For some reason just after launch, it goes to torque source 4 for a split second, closes the throttle blade, then recovers. It's obviously not hitting a rev limiter. Can anyone suggest what to adjust in the tune to keep this from happening? Thanks.
FYI, car has a transbrake and a 2-step module installed.
