He de-catted the head pipe already......what warranty?

No matter what tune the SE tuner gives you it is still to lean and has to satisfy the EPA. Power Vision hands down

"Too lean" for what? A tuner hardly unleashes hidden power and the factory stand by their stock, lean motors for warranties.

So, what are you trying to do? More HP? More Torque? Better red light drags or better 2 up touring? Just going an getting pipes, intake and a tune without knowing what you want to do.......

If you purchase from Fuel Moto they provide a map with tailored for what you have done to the bike and support when you change it. Power vision support fro fuel moto is out standing.

I think with SEPST you can adjust AF ratio at any or all RPM and speed settings and make it more rich than you want. Is that incorrect?

incorrect is my understanding..and the whole point of it having its limited capability is to make sure it can't operate outside of EPA parameters / standards

My understanding was that the New SE tuner released after the 2017 EPA decree only changes the timing. It does not change the fuel air ratio like the previous SE race tuner did. I could be wrong but this is what i remember.

I have one, bot in 2018, and used it to enriches AF after downloading, for both stage 1 and stage 2 upgrades.

I certainly don’t run lean with freer flowing AC and exhaust. If anything, I’m a bit rich.
