It is likely you are missing some limits, could be torque, airflow, rate of turbo acceleration, transmission. Hard to know. Probably best to log a support ticket with all the details, infolog, debug, logs, tune file and see if they can locate and add. I do see when we supercharging the Y62 similar limiting on the throttle in 1st that we don't have access to, but it is worse with traction control on.
