Got my ECU back last Tuesday and got it hooked up. Bike started fine, so my wife hopped on and we rode about 30 miles to where she rides horses. I wasn't blown away like so many other people have been. I felt the like the bike responded better, but with the wifey, it was hard to tell. After dropping her off, I ran solo for a bit and started to feel what the hype was all about, but still wasn't blown away. Since last Tuesday, I've had the opportunity to ride several more times solo, and I've become a Believer! The bike pulls all the way through the throttle. TBH I think I was being too timid on the throttle at first...you really have to give it some gas, but when you do, better hold on. Great upgrade! Well worth the $$$. Thanks Steve....can't wait for Evo II!
