The turn around time was phenomenal (the day they got it they reflashed and send it back), the packaging of the ECU was done in a very professional way. I plugged it back on the bike and took off... I did not leave the subdivision before I could tell it was "better". It was just so... Smooth ! No popping from the exhaust or notorious psycho throttle behavior from the slightest twist of the wrist. As far as noticing the bike to be faster... I couldn't. This bike always spun the first 2 gears anyway, and I'm not a 1/4 mile guy so to each his own.

Wow, what else can I say. The power band from top to bottom was excellent. I could lug it in a high gear and when I needed that instant, extra passing power, it was more than there. I found a stretch of road where I took up to 150mph and she got there effortlessly, like the Hayabusa (just more wind-shear).

Too much to enjoy now and it's all thanks to you Tim. I can't wait to see what's next !
