Im sure I wont be the only one to say, but you pretty much bought the wrong car. the ///M is a beast in its own way, its low end torque is part of its character and even though I've done every bolt on mod, it still doesn't have CRAZY low end torque like a Corvette or Mustang. But it has an 8400rpm redline, and that will make most, very happy!
