I've heard people mention that a transmission needs to learn after getting a tune and never understood that statement. I've had half a dozen handheld tuners and also a handful of my autos have had dyne tunes and not one of the handheld tunes "learned" anything after miles of driving on said tune. My shifts were as hard 10k miles after loading a tune as the first mile after loading a tune unless I adjust the tune by changing shift points on like I could on my handheld SCT for the two 09 G8 GT's I've owned.I've been using the Livernois 87-89 performance tune. Haven't had the chance to put many miles on it since loading it but dang it wakes the truck up. The shifts are harder but that is due to not putting enough miles on the tune for the tranny learning. There are many others running these that can chime in.

It'll definitely smooth out the more miles you put on it. If you run the soft shift tune it'll shift smoother just like being stock. I've had the 91-93 performance tune in for over 6 months now and it shifts a little harsh once in a while but definitely much smoother than when it was first installed.I've been using the Livernois 87-89 performance tune.

LivernoisGroo here
I know many use 91/93 with tuners but 91/93 is very pricy here so what do you get with an 87 tune?????
Not recommended as your tailgate damper could overheat. ?What happens if you put 93 octane when you have a 87 octane tune flashed?
