The one time I tried Bluecat, the shift scheduling was earlier than stock! Probably had some values off, will try again.
However, the 2015 shift scheduling is noticeably better than my stock 2012 tune. I recently got a 2017 tune to look at, and it looks more better (lower tps areas have shift mph raised) Because I often make a turn and the transmission shifts right when I want to punch it out of turn.
Still working on the 2017 tune because there are some other differences I'm still looking at. For example 5th and 6th TCC disengage is set much higher than engagement speed, in effect not disengaging. I believe it is set to downshift with tcc locked? and so the tcc wont disengage until 4th or lower. (i think)
The biggest thing I don't agree with, that many recommend, is disabling tcc in 1-4. For me, 4th is my around town cruising speed. (with 3.08 gears!) Having converter slack when you want to make small speed adjustments is annoying, not to mention generating more heat. I am speculating those that turn it off in 4th, dont do much in town driving.
Remember to reset your adaptives after a tune!
