We tune them.

Hey Jenna, do you happen to know what kind of power gains I can get out of a 5.3 with a 6 speed?

We are seeing 10-25HP, depending on fuel (octane and quality), and modifications.

Diablosport is the way to go. I have more power and better gas MPG 3 to 4 more. I tested it out 2 weeks ago. I put it back to sock and my gas MPG went down.

Tim, do you happen to have the 6 speed tranny in yours? Mine's the 4 speed but from i've read in this thread having the tranny tuned as well helps out a ton (which bb does but not diablosport). Just wasn't sure if just having the 4 speed tranny would make a difference in what tune I ended up getting....

07Burb I have a sixspeed tranny with Airaid. When I ordered my Diablesport the company said that I have to have a special program because their was only 400-500 hundred yukon's with the Engine mods that mine has. Not sure what they are.

Thanks for the info, Tim! Not sure which route I'll go yet now that I've read the info you've given about your tune. I guess it's good that I don't have to make that decision real soon
