HMF has one... HMF Exhausts / Shop / Accessories / HMF Optimizer
6 HP+ might be just a little optimistic with just intake and exhaust mods and a programmer. If you were starting out with 70-80hp I could see that much improvement, but with 44hp I think that might just be a little on the pipe dream side of things. I hope I'm wronganybody know if any fuel tuners are out yet for the 570?I know when you start doing exhaust and intake mods the fuel is gonna need tuned accordingly.razr 570 fit our motors or nobody knows yet?i know these motors were never meant to be competition but intake and exhaust mods with a programmer should be good for finding 6hp plus without going into the motor.nearly 600cc:biglaugh:
