a couple weeks ago me and one of my friendswent out and raced, hehas the exact same mustang(v6,2006,auto) except he has a brenspeed tune, cai, and a flowmaster a/t axleback. so we figured he'd win but weren't sure by how much, suprisingly i won by about a car length. we raced again a couple days later at a light and this timei won by 2. so i figured he was just a bad driver but yesterday i pulled up next to another v6 with an axleback, and maybe more, it was also stick, well he had me at the start but as soon as we hit 30 i started catching up really fast and he was in my rearview mirror by 60. any comments as to how this is possible. the only thing i have done to my car is i took off the axle back.
