Its like i have a whole new bike!!

I was totally blown away at how easy the install was. And that includes getting the map set up and the bike running again. I am very computer illiterate! And it was quite simple to complete the process.
The performance gains and super smooth acceleration are noticeable from the very first rip of the throttle after a good warm up. And seems to be getting even better with about 300 mls being rode since the install.
I am more than happy with my purchase! Just wish I had a xxxl t shirt with the ThunderMax logo on it. Sure would make the world a better place... lol!
