I have a 2007 2x4 tahoe with 167K miles. It still has the AFM and is bone stock. I'm looking to do a AFM/ DOD Delete, along with a stage 2 Texas speed cam. throwing the idea around but not sure if its worth it or not. What do you guys think? The Tahoe has never given me any problems. I do regular oil changes and the mileage is all highway.

Thanks!

 

I too have a 2007 LTZ in pristine condition. But it has over 140000 miles. I’m torn between just doing PM (water pump, hoses, timing chain, AFM delete, etc.) OR doing a complete rebuild (keeping 243 heads but add moderate cam with AFM delete, new lifters, etc.) OR just swapping in a new performance crate engine with trans. Money isn’t the prime driver for this decision but I want to be sensible. Not really sure what the smart move is.
