Ok let me look that up for you to make sure what they tested. Had nothing to do with whether they sell it or not.

If you re read my comment. I didn't say no right off. I said it might work, but would be VERY restrictive compared to aftermarket non EPA compliant tuners. Therefore IMO would be a waste of money in the context of whether your warranty was voided or not. Aftermarket cam already voids the warranty, so why not get your money's worth out of a 400 dollar tuner.

But that's not a fair/direct comparison because of the exhaust; the SE tuner didn't have a base map.with a comparable exhaust.
I would love to see a good tuner take an existing EPA-compliant SE stage-equipped.bike, and show us how much more can be gotten out of a full tune! The day my warranty is over, I plan an doing that, but I would sure like to know if we are looking at 2 HP or 20 HP gains from the tune!

When most of us talk about cams and tuning we are still living in the memories of our Twin Cams. The TC was noticeably hobbled by the factory tune and a lot more was left on the table. These M8s are far more efficient and better running to begin with. They are no longer overly lean from the factory. It’s part of the reason the stage 1 makes a remarkably smaller difference than years prior. So, while you can absolutely get more out of aftermarket parts and tune, the SE safe option is not the same depressing choice it once was.
If you’re trying to keep your extended warranty intact, the SE cams/tuner will 100% put a smile on your face. Sure it leaves a little out, but it’s not junk. It’s a decent compromise compared to years past. When your warranty runs out down the road you’ll be ready for a bump maybe...go aftermarket then and get a second “new bike” smile out of your paid off M8. Just a suggestion.

that's an excellent summation.
I hate telling lies, and trying to keep the warranty could turn into a lie-fest.
you are right, do the SE cam & tuner, and just enjoy it without worrying about having to fib about stuff.
and prolly be too lazy to do anything else later, esp as good as the M8's run now.

Its also known that some of the SE parts are inferior in quality as well.
But yes. For someone worried about their warranty, stage 2 or up gives a decent return in performance.
