    Damn. I don't wanna buy a chip if EFI can tune it. And really that's what I got EFI life for, GM stuff.

    Mate, there is just nothing straight forward or simple with what it takes to support an ECM, that 2.8L ECM is a new fresh design and will take a lot of hours to figure out how it works. Unfortunately with GM currently running 6 different ECM's on their late model petrol engines we battle to find the time to start on a fresh project like the Colorado ECM.
