I installed Bill's kit in my 07 Gade HO p-tek. The slep is much snappier in all RPM ranges. Between 5-8 K RPM it's a monster. After a day of riding, I feel like I have been in a pull-up competition. I'm not a big mod person and this is the first time I modded any sled I owned. I'm happy I did.
Bill is great--bottom line. YOU need to let him know what YOU want the sled to do. He'll take care of the rest. One other thing. Follow his directions exactly, I did and didn't have to mess with anything after install.
Shipping is lightning quick too. Ordered on a Friday afternoon, I received the kit on Monday!
