Just picked one up for a great price

[tights24]

Howdy folks,

Just picked up a Trinity and should receive it Thursday. I have a 2007 Yukon SLT 2wd. Any do's and dont's with certain tunes? Curious what other folks are running and their current settings for the 5.3 4spd. To add, the only aftermarket I have on the truck is an Airaid Jr. CAI in case that makes a difference.

Also, can someone PM me with a cost associated with any custom tunes/settings that I wouldn't be able to do myself? Finally, if and when I do a custom tune, would it be stored as such in the trinity? Meaning, would I then have my choice of the boxed tunes as well as the custom?

Thanks for any and all input.
