The auto is shifting normally now, so it is like I'm driving my stock drivetrain with more power. Definitely happy with everything now that the transmission has stopped acting up. While driving on the highway, I can actually hear the whooshing of the supercharger boost kicking in on moderate inclines while the transmission holds in overdrive. In the past, the transmission would downshift into 4th or even 3rd gear and all I could hear was the engine rpms winding up. I no longer need to manually shift like I did prior to the transmission TCM reprogram. Much better overall experience.

Now that I can hear the boost instead of the engine rpms winding up, I don't have to rely on my boost gauge as much. I'm mainly using the gauge to monitor my air fuel ratios instead of verifying that the supercharger is actually doing something.

I've discovered the only downside now is the cost of using premium fuel and losing about 2 mpg. I can live with that for the increased power.
