Wanted to report back with some figures as I was a little skeptical as to how much of a help the stage 3 was going to be. I'm on GCs and prior to the stage 3 flash I was only able to hold 24psi at redline and it would typically slip prior and post shift starting in 3rd gear.
After stage 3 flash, I was able to run 26psi at redline at the track yesterday with no slippage or at least I couldn't feel it enough to detect.
Did I also mention, the car is an xi with 115k miles, tuned since 15k miles, GCs since 110k miles, and original engine/transmission. Just goes to show if you take care of your car, she'll take care of you. And I know I'm on borrowed time but it shows the the longevity of many of these drivetrain parts.
Here is a run against a CTS-V and don't mind the date stamp, this was from 4/15/17
