Not running a limited, but have '19 Max Cab XT. I haven't tuned it so far, but replaced the Primary and Secondary Clutch Springs with ones from EPI Performance (CAPS2/QRS2, inexpensive mod at $60) when I up'd my tires to 30x10x14 QBT 846s. In normal mode I've had it up 57mph (seems to be accurate according to GPS), never really pushed it all the way out, mostly run in Eco mode when around town. The throttle response is a ton better at takeoff than stock. RPMs are decent, not wound out real bad. I may or may not tune it in the future, pretty happy with it so far. 1700 miles on it at this point.
2020+ models have 10hp up on my '19 and I've read a lot of good reviews of these machines being tuned.
The amount of space inside is really nice, turning radius for that big of machine is great, and options on how to set it up is killer (Spring/Summer as a trail and yard maintenance machine, Fall its a hunting rig, and winter life a plow truck).
Only real dislikes are the back door windows don't roll down (which isn't a huge thing, but disappointing), 650 amp stator (Limiteds have 850 amp), and too many rivets to remove skid plates. With my ATVs, I liked to take them off once a year to really clean out the under side. Soon I'll just pull them all and replace with rivnuts and/or aftermarket skid plates.
