Power for 6.0l Vortec
Forget most or all of the programmers....give a shout to BlackBear or go to blackbearperformance.com. He will tune your truck to your specs...you can get a generic tune or he will go with you and u drive your truck with him having it hooked to his laptop....he will record everything about your truck, then tune it for best mpg, power, trq and best driveability. You want to wake up the detuned vortec......he is your man. Every truck is different and he will tune for yours. Did my 07 classic 1500HD with the 6.0....idles way better, better 2-3 mpg, better throttle response, better shifting and oh boy when you step on it....well it just pulls and pulls....watch the wife grab the dash lol.
