First Tahoe, but no stranger to full size GM SUVs: '89 K5 a long time ago and just sold a '91 V2500 (3/4 ton, 4x4) Suburban, last year of the squarebody. The burb was pretty well built up, 383 stroker motor, later model 4L80e, lots of TBI tuning etc, but I just wasn't using it and wanted to move onto something a little more practical with more creature comforts. (Plus my wife never liked it and she loves the Tahoe)
Tahoe is '09 LS, 4x4 - has just the options I want and nothing more. 5.3, Heavy-duty cooling, locker rear, etc. Good color, too. Has 192K, but I'm not afraid of swapping in a long block or even rebuilding. Same with trans (although I wouldn't rebuild that myself). I was specifically looking for an '09: 6L80, but still has a 2 speed t-case. Runs awesome, no significant issues. I already put on new Cooper tires, swapped to a CarPlay stereo, fixed cruise by replacing the brake switch, added factory style fog lights, and several other odds and ends. Not sure what the long range plans are, 6.2? Turbo? We'll see, just going to drive it for now.
When I first got it I noticed AFM never seemed to come on - dash readout always said "V8" so I'm assuming it was disabled in some way. The weird thing is, I've worked with a tuner in town in the past and he looked inside for me and said that the tune has never been touched. So how would AFM be disabled if tune is totally factory? He has since disabled AFM in the tune so I'm good to go, just curious and want to find out if someone's been in the engine.
