I will throw my 2 cents in!
I have the SSERT R.T..
Nother fellow CVO'er previously had the SSERT installed, Dyno'd and results were quite impressive.
His map gave my dealer a starting point for tuning my bike. We have a few differances especially in exhaust but that is our major difference
My Results were minimal Dyno time, and a good tune.
Dealer gave me the Box, a C.D. copy out of their Dyno with my map.
I do not have the expertise, or a Dyno to do any tweaking.
I feel that if I come up with any issues on the road, I should be able to head into any H.D. Dealer and get my problem resolved since they understand the SSERT.
I maybe a little Gullable, however, I hear a lot of road issues out there with After Market Tuners, and at least feel that if I need help, it will not be compounded.
I was also told from my dealer that Warranty, and Ext. Warranty stilll holds with the SSERT.
