I'm getting a dyno tune tomorrow. What all will they do to my car. How much of a difference will I feel I know because I'm auto it willeffect me more because they can adjust the shift firmness. But what else will all be done.I have an automatic 99 GT. I'm also getting 4:30 gears installed and I have slp lm2's and a o/r H pipe.

 

anyone know?

 

You can get a 93 tune with advanced timing, perfect fuel trims, make sure A/F is all perfect, etc......

But it's not gonna be anything overwhelming. You car will run better and more efficiently. Not sure about the shift point, since i've never rode in a tuned auto. Good luck

 

anyone else know who has an automatic?
