Don't have the printout in front of me yet (their printer was at their other store yesterday), but when the tuner showed me the hp/tq results of my dyno tune yesterday on his computer screen, I sure was disappointed. Somewhere around 43 whp before the tune and about 58 after. The tech told me that the heat really affects the hp. It runs great, better than before, I just can't imagine the heat (weather) would have that much affect on the numbers. I thought the stock whp for my bike should have been around 63. Tech said when the weather cooled off I could see as much as a 20hp gain after he tweaked it again for free. My set-up is listed below the pic of my bike below.[:'(]

 

Those pipes may sound good but arent helping your #s.

 

The pipes are baffled and the performance has improved (can now pull ahead of my buddies bike, when his used to pull on mine) so they definately aren't hurting the performance.

 

Hate to be the bearer of bad news but on a stocker they sure are. If he is promising 20 hp because it's hot out, be careful if he tries to sell you a bridge.
