What axle you guys running and which version tranny tune version are you on? I have 3.55's on stock 20's, and when I ran .30 Easy tunes with S1L, 4TC was at 35mph (perfect) and 5TC seemed to be up at 51-52mph on light throttle. My problem was I have a lot of 45-50mph driving, so 4TC rpms was up there and i found myself 'speeding' to keep it in 5TC. Same experience as you with the 55mph shift point when I tried S1M. Shifts never smoothed out and were rough. Maybe Easy tunes don't work with anything else other than its default.
I'm now on S2L and it shifts smoooooth and nice for daily driving (to the track of course) . 5TC kicks in at 48mph even when I'm at about 25% throttle and it feels like it lugs a bit. It's perfect on light throttle. But I'm in 5th with no TC driving at 45mph; rpms are a bit high with no load and there seems to be some indecisiveness shifting in and out of TC if I happen to drive around 48mph. It would e great to have a little more 'hysteresis' if that's the term for it.
I was going to try S1L again now that I'm running default 250 tune. I like being able to accelerate like a rocket starting in 4TC
