I haven't tried it yet but if you have a stock tune for an 07 Suburban, that's what I need. There is nothing left on the 'burb from the 5.3 flex fuel. Everything from radiator to fuel pump intake to...

Not a factory tune yet. Would really love to find one to compare it to the truck version. Shouldn't be that different but I feel some slight surging at mid throttle with the truck tune. Also a...

Used a local tuner in the beginning to help me figure out the VVT issue. He put together a start-up tune for it but it did not run well (other issues were contributing). Then I found the factory 07...

Forgot to mention the ECM and TCM from the Suburban are already licensed under EFILive, ideally I would like to keep those in the truck. Also thought about swapping the pick-up for cam reluctor...

Changing out LC9 and 4l60e from '07 Suburban. Got an L76 and 4l70e as a lift-out with wiring harness, ECM, and TCM. Thought it would be a direct swap and just recalibrate my current ECM/TCM for...
