I originally had a ThunderMax and a Zippers high flow air cleaner installed on my 2009 FLHTC during Bike Week 2010. The motorcycle already had a Klock Works set of mufflers on it.
That week I rode the motorcycle to Texas to cover a event there. I was very impressed in the increase in performance.
I have over 18,000 trouble free miles on the motorcycle since the install and continue to be pleased with its performance.
Just prior to Bike Week 2011 I installed a D&D 2 into 1 exhaust on the motorcycle.
I used my laptop to tell the ThunderMax of the change and then went for a ride as the engine re-tuned itself.
Besides the performance increase I am very happy that the motorcycle does not have to be run on a dyno to tune it.
What is the HP increase on average with the Zip Kit? Does anybody know? This is usually the most amount of HP gain for the least amount of Do$$ars !
