well i am interested in a tuner for my truck since i changed out my tranny from a 4r70 to a 4r75 and do to this change my truck cuts off within 30ft of driving, would a tuner allow me to change my tranny option, and which is a good custom tune.

 

You will need to contact one of the tuning guys and discuss it. You can find lots of info in these threads on the main 3 that program these trucks.

Mike Troyer at Troyer Automotive - Uses the Xcal2 and 3
Justin at VMP - Uses the Xcal2 and 3
Bill at Power Hungry Performance - Uses the Gryphon

All three are top notch and will be able to help you. I would do a search on them in these threads and contact the one you think sounds good.

I have my preference, but you need to look for yourself, to fit your needs.

 

thanks for the info man

 

You're welcome.
