It is especially likely in auto mode, as the least bit of tire slippage kills power when in default/ auto.CastleCat, you can still hit the rev limiter in Auto mode. If the tires can spin in Auto mode, or any mode, then you can still hit the rev limiter. The rev limiter is designed to protect the motor from over-revving due to a driver's failure to shift or when the tires are spinning up so fast that the transmission can't upshift fast enough. The rev limiter is a good thing. Roll into the throttle, don't smack it.
