My bike is a stock 05 with the 20222 tune. I installed the GiPro on Sunday and have been enjoying the significantly better power and throttle response, but I couldn't say it was enough to elicit a "wow" from me. I have been doing a lot of hard accelerations to explore the new power and the wheel has come up a little, which was more than it would do without the Gipro.
Today though, I was rolling along at about 10 mph, in first gear clutch completely out when I cranked on the throttle hard and the front wheel came up almost to the balance point before I got off the throttle. Now that elicited a "wow", actually it was "oh sh#t Hellfire was right." That is just frikkin amazing, no need for tricks like clutching it, fork rebound, or putting your weight back, just add power hard and up it goes. I have never had a bike that would do that let alone an 800 pound cruiser that sounds like a sewing machine. I have new found respect for the beast.
This first tankful of gas with the Gipro has been nearly entirely city riding since I wanted a lot of stop and go for obvious reasons. Ordinarily with city riding and not accelerating hard the fuel light would come on between 120 and 125 miles. Freeway riding it comes on between 135 and 140 at 80 mph. With the city riding and all the hard accelerations from experimenting with the Gipro I expected the light to come on at about 110 to 115 miles, but it came on at 135 miles, WTF?
Hard to believe the Gipro would give better gas mileage too and actually I still don't believe it yet, I will know on the next tankful when I will ride the bike "normal" and see what happens.
