I have both Bama 91 Race and Tillman 91 Street race, both feels awesome, Tillman seems to pull harder over 3000 rpm, Bama gives you lots of torque and then stays steady at high rpms. This is just how i feel. Im going next week to a dyno and will compare Bama & Tillman 91 race to see which one gives you more Hp Trq + air fuel ratio.
