Listen to what Bosch says. She knows what she is talking about. One of the best mods I ever did to the '03 GT was stage 1. If you take a stock GT and a stage 1 GT and drive for the best mpg the stage 1 car will win. Stage 1 gives you more torque so it will take less gas to get going because of the added torque. It is also true that if you have a lead foot you will get worse mpg. It all comes down to the foot.
