Got my Dobeck TFI installed and finally got to take her for more than just a down the road ride. WOW!! Someone here said it was a seat of the pants noticable improvment. I couldn't agree more. I was a little sceptic at first and even thought money wasted, this was the impression I had just riding up and down the road a couple of times. Today I got to put 75 hard miles on her and it's almost like a new bike. Throttle response is great, low end torque is improved, engine runs smother, and the biggest improvment is in 5th and 6th gear no stalling no hessitation just get up and go. Thanks to all who posted and answered so many questions about this product.
