06 Yukon Chip Mod

[metalliclounge]

Hey everyone, new member here! I am the proud owner of a new 2006 GMC Denali AWD 6.0 engine. I'm looking to improve gas mileage and curious if anyone has had any success doing a chip mod? I searched around and didnt see any posts on this here. If I missed them sorry. I already ordered a cold air intake and looking to squeek out as much as I can.

Thanks for any help!
