Interesting discussion, but..............
There are many aftermarket systems for the newer bikes discussed many times on this forum.
There are pros and cons to ALL of them. There are pros and cons to the Harley OEM system, in fact, there are pros and cons to ALL OEM systems from ALL manufactures of ALL cars/motorcycles. Why do you think there is such a huge market for add-on's or mods?? Even Ferrari products are modified by some people!
SEMA has a show every year that is huge! There are many people that just HAVE to modify things!
Getting back to Harley CVO (this forum), the members here have the most expensive Harley on the floor, and STILL can't leave it alone! I personally think it has something to do with all the snow back East, but, that's just me!

None of my bikes make 150HP, and I don't want that. I want a smooth running touring bike(s) and make my changes to suit my riding style.
I used Mastertune on the '09 and the '10 bikes, works fine for me
except it is more complicated than I think it should be!
I'm going to check on some of our other members using other tuning devices, just to hear THEIR feedback. My buddy has the V&H power pack on his '08, and loves it.....
Different strokes for different folks, right?
You guys responding to this thread need to quit sugar-coating your feelings, and let it out!

Of course, this is JMHO!! LOL
