I've had my SERT for 7yrs + and I love it (O)Zero issues in 7yr and 47 miles and I don't/Havent had have to Fudge with it at ALL...

I'll add,,, We do have a Great tuner at our dealer..

If,, I buy another bike.. I'd install the SEpST mostly because its ever better and once set I wouldn't have to Fudge with it either.....


just me...

 

ThunderMax is the ONLY way to fly........i won't ever run anything else.

 

I have the vigilante EZ and it works great with stage I. If you are going past stage I it is not the tuners for you. I ride with a guy that has a 2011 103ci that is stock. In the past I could not keep up with him passing in the mountains. I have installed the EZ, V&H bigshot staggered and S&S stealth air cleaner. I can know at least keep up with him. He would still win in a race but I can hang with him. Gas mileage seems to be slightly lower but I haven't checked it officially.
