I know the tq tune produces its power in the 1500-3000 RPM , the Performace produces its power above 3000, and the Race tune produces its power throughout the RPM range. In a drag race, wouldn't be better to use the performance or race tune. With street tires normal launch is in the 2000 to 2500 RPM range. In no time at all you are above the tq tunes pwr and into the per. tune range and remain there for the entire race.
