I agree. I think the M8 is a nice setup in stock form. And I think it's the best Bike I've bought from HD.
With this bike, I'm going to do a fullsac header, S&S mufflers, S&S Stealth intake, and a woods cam. And I'm going to tune it with the TTS. That's it.This bike doesn't really need anything, but I can't leave it alone.
The stage 3 with headwork was ok on my 15. But I think I could have done much better for less with the aftermarket. I wasn't happy with the sound or the performance, for the amount I spent.
I used the HD parts in case I was on the road out of town and needed the dealership to fix it. I'm not worried about that this time.
I had always used aftermarket cams in my bikes before the 15, and was always happy with them.
As far as numbers SE vs Aftermarket, I'm not sure, but I would think you would get better numbers from the aftermarket.
I think with the aftermarket tuners , there is more adjustments the one tuning can make. But from what I hear, it's whichever tuner they are more comfortable using.
