I've read that the tune raises line pressure for all shifting functions even where it's not needed but I get the benefit of optimizing performance of the catback.
The valve body upgrade fixes only what needs to be fixed. I'm taking a trip up the Right Coast anyway, I can easily stop off at Level10 to have them knock this off in one day.
My focus is primarily on the crappy shifting of the 7AT.
