7AT shift improvements - tune or Level10

JenovaI

I'm really interested in your comparisons on the Uprev vs ECUTek.

I have a 479hp Stillen SC 7AT with Uprev tuning and I feel like the shifting is pretty amazing for an automatic. TBH I'm not even sure Church's in long beach did much to the 7AT when they tuned for the SC. In D it drives like a normal car, sometimes it hangs in 3rd or 4th a bit longer but no biggie. In M it slams into each gear like it thinks im drag racing.

I'd be interested to see if a different 7AT tune can do it better. Can i even mix and match tunings like that? Church's Uprev on my HP is amazing, gained 55whp over Stillen's SC tuning. Don't want to lose that. I obviously don't know much about tunes lol.
