how was your trip-i have 2-1 arrow -airbox removal ai removal-powercommanderv-about 5 hp rear wheel after one half ass dyno fix -i will take it back and do the 6 hr tune with 200 rpm increments-i don't know if it will gain more but there will be no flat spots-i gotta say a lot of money and time for 5 hp-but it really seems to have a lot more snap and is a lot more fun-i raised the shocks 10mm and that really made the bike fun

My trip was just great after the first day, lots of great road and the weather was from good to great... Tybee Island was nicer then what I had expected.... for blueridge I am speechless,,,, worth all the effort involved. you have to know that on our first day the thermometer was around freezing point and raining so it was hard.... But over all met nice people and riding on us road is just a blast here the roads are so third world like that it sometime take the fun out of riding....

I dont change my muffler to gain power but because an idiot backed up on my bike so I have to change them so might has well go for something else....

Any one knows the answer... I read the post that bleach indicate but I am not technical enough to understand what they explain! Hp indication will be fine for me .....

On a stock EFI motor you're getting 56-60hp, depending on milage and dyno shops. With the installation of TORs and remapping the ECU you can gain between 6 and 9hp. That is good bang for the buck.
