The constant locking and unlocking of the converter on each shift, the short shifting, and soft shifts really leave a lot to be desired imo on a performance car. I want my performance car to shift firm, fast, no short shift, and I don't want the converter locking each gear part throttle pulling on the motor.

Hey King, with the factory A10 trans tune as you described kinda sounds like extra wear and tear by GM in order to achieve max fuel economy. Does your performance tuning actually save on excessive wear while providing the shifts that we all want?

Thanks,
