Thunder max and warranty
Not being very educated on modern day bikes being I rode a carbed bike up until 2020 I have a question. I’m looking at tuning options on my bike and I’m not crazy about screaming eagle stuff, I saw that Thundermax is a replacement ECM, will there be an issue if I need to bring the bike in for warranty work, if I reinstall the stock ECM, will there be any red flags.

The theory I read was the speedo counts cycles and when you put your stock ecm back in the cycles and mileage will be different. Red flag and likely your warranty will be in jeopardy. Just fair warning if you do go with the thundermax there's not alot of map combos available. Did an installation for a guy a month or so ago of thundermax that he got from fuelmoto thinking he'd have map support from them...we were referred to thundermax support, who were great to work with and the system to send data collection and receive revised maps is very easy to use.

I can't speak for the warranty side, but I've had a T-max on my previous bike and strongly looking at getting one for my current ride. But, I'm well out of warranty.
As for the S.E. vs T-max? I prefer the T-max. My springer has been upgraded with the S.E. cam plate and 203 cams. Also had the Stage II tune uploaded. Still has a few spots that are less than optimal (misses, sputters) and if it had O2 sensor bungs in the exhaust, it'd have a T-max already! Last bike had the same problem with a S.E. tune. I feel T-max gives you just as much tunability (maybe more), it just does it differently in the way the maps are laid out.
checked on dyno tuning at my H-D dealer and it'll take $500 to get the bike tuned. Then, if I ever change anything, it'll take ANOTHER $500 to get it right again. I don't plan on going big bore or anything right now, but I've got a set of cylinders and heads for when that time comes. If I put a T-max on the bike, it'll cost the same as the two-fer dyno tune, but I'll have wide band adjustability for altitude changes, as well as the ability to tweak things to my liking, not what a dyno jockey thinks is best.
So far as finding a map, get one that is closest to your setup and do a few auto-tunes. It'll adjust the A/F to get to the pre-set ratios. Then, you can go in and richen, or most likely lean out the tune in specific areas to get the best mileage and torque at every part of the throttle. Hardest part of "tuning" with T-max is not touching it until you've put enough miles on the bike to allow it to adjust to your application!
Lots of benefits, but as I said, not sure about warranty stuff.
