I have a GT auto with SCTX3 Bama tunes. I looked at the options on the custom tunes and one of them says "shift firmness" followed by percentages. What does this adjust?

Thanks!

 

It adjusts the pressure that you feel relative to that upon a non-advanced pressure shift. In other words, it makes your shifts feel that much firmer. A higher percentage will be rougher on your tranny and axle, but will be more fun. You won't mess up your car playing around with it so have fun and let us know how it goes.

 

Thanks. I just spent an hour changing the settings and test driving. Learned a lot and am pleased with the outcome!
