Your mistake that you're thinking is that I mean low end as in the commonplace cruising rpm when I really mean low end torque for getting off the line. Do you really think in a 3,700 pound pickup with a 4 speed and 5.30 gears that I'm going to be leaving the line at even 3,000 rpm? No the 2 step is set at 5,000 so as low as I have torque when the engine finally has the load put on it then I'll call it low end. It's a full blown race pickup and that's why I went custom grind
