Ive got a 99 5.7 Tahoe and looking to do a custom tune, but before I do I want to make sure everything is in good running order. I dont have a CEL and maintenance has been kept up since bought new in 99. Does anyone have a factory profile and parameters they can post I can refer to? Thanks guys

i would suggest the following:

1. Make sure that the fuel pump is working good
2. Check and repair any MIL light
3. Make sure that u have good spark plugs and wires
4. Maintain fuel level 50% in the tank as min
5. Make sure that the intake piping are not leaking, especially after the MAF
6. Make sure that the intake filter is clean
7. Fix any exhaust leaking or blockage in the system
8. Replace or remove the cat's if ur regulations permit to do so....
