Smart Tune Pro and a Stage IV 131 ?
For the next year plus I have to stick with Screamin Eagle to keep my warranty intact, and I was looking at the Smart Tune Pro. My 19 Street Glide already had the stage IV kit installed when I bought it, and it runs good, I have no complaints, but of course Im wondering if it could run better...I know you can do more with some aftermarket tuners, but like I said I want to stay warranty compliant for now. From what Ive read it looks like it comes with everything you need except the Pro Street tuner, which was included in the sale. So are they worth the 400 bucks ? Would I see any improvements? I have very little experience tuning, having only done a few auto tune sessions on my previous bike along with loading a stage 1 map, so Im basically a newbie at this and dont have a lot of time to dedicate to learning more about it right now, which was another reason I was considering it- Id rather spend my time riding than tinkering. Thanks for any help

Either way you end up with an EPA compliant tune. Not worth $40 let alone $400 imo. A waste of a perfectly mediocre EPA compliant stage 4 kit.
If you want to keep your warranty, leave the bike stock til it's not under warranty or you're just pissin' in the wind imo.
There's no such thing as auto tuning either. Just maintaining the half assed one you already have with the street tuner.

What year bike? If m8. There really isn't a reason to map the VE's with wide bands with the SE tuner. Since you can't change the target table and narrow bands are perfectly capable of hitting the target.

Smart Tuner will affect the entire RPM range based on weather/ altitude. Yes, it has to stay within EPA legal tune, but in will prevent an over rich/ over lean condition that the Tuner cannot do by itself. The narrow band O2 sensors only correct for light load and cruise conditions once outside of that, the map loaded in through the Tuner takes over and it is fixed regardless of weather/ altitude.
