Sorry for the slow reply. Thanks for the answers. The 2020 redeye challengers and 2021 redeye chargers have a line lock limit that is settable. Trying to save the engine from an over speed. I have the trans set to limit in manual mode to 4500 to 4th gear and hold. Use the line lock and it goes to my set rpm. I want to get away from foot braking the burn out. No I wonder how much in the newer calibration wont play nice with my non redeye car.
