Ok, it's 44 degrees here, so I decided to take the bike out. Been super anxious..Well, this was a GREAT mod!!! My bike responds like no other. Rolling like 5 grand and snap the throttle in 2nd, right in the air. I hit a straight road..1st, straight up...I let it drop, clicked 2nd and twisted, right back up, but it was managable and slowing getting higher. I clicked 3rd and it was still airborne. It accelerates insanely fast!! The TQ diff alone is worth it...Also, I did not change my map and it is running great. No surges, stutters, nothing...I can't wait until it gets warm so I can really beat on it.
