Here's a review of the stage V kit. There are more on the HD online store:
After some ( a lot) of research, I decided to upgrade my 2010 Ultra TC96 that had already been tuned after addition of a full exhaust and stage 2 screaming eagle air cleaner and was making a respectful 82 lb/ft of torque @ 4400rpms. Since I ride 2 up 50% of the time and in the Hill Country around Austin, Texas, I wanted the power to conquer the 6-7% grades which are common there.
Well, I'm 275 miles into a 1k break in period and I couldn't be happier. My local Harley shop(Kingwood HD# did the installation and after several in house heat cycles, stuck it on the Dyno for a base tune.
How about 107HP and 112lb/ft of torque out of the box? My total cost, including ACR solenoid and discounts came to $3748.17. By no means cheap, but even with having to keep it below 3500 for the break-in period, the transformation has been nothing short of unbelievable. For a 825lb bagger, I could not believe the difference. And, can't wait to get the miles on it and take it back for the final tune. The 259E cams are supposed to be a high torque cam, but it has an angry idle that is absolutely music to the ears! This up grade is the best upgrade I have done on any Harley I've ever owned#I'm 61 and have been riding for 42 years) including the Ultra's Garage roommate, a 2005 Screaming Eagle V-Rod that makes 117Hp and 85lb/ft of torque. I suspect the V-Rod is going to have a lot more quiet time to itself very soon.
