Got my ECU today after a little snafu on the part of Guhl, but nothing major. As far as the dealer goes, Lloyd was great. Awesome communication, easy payment with Paypal, and he was there with the little snafu. I highly recommend that if the deal is still being offered, its totally worth it. Save some money, and go through Mr. Rivers.
As far as the tune goes, it does make a difference. Huge improvement with low end grunt, and I do feel a little more with mid range. Not really sure about any improvements with top end power because I only rode it around for a bout 20 minutes or so. But that's ok because I was really only looking for low end grunt, and this tune delivers. Just as a note, I also installed the BMC race air filter and V&H slip-on at the same time but I doubt that they are contributing to much if any of the felt results.
A- mod from an A+ dealer!
