Which tune will give me the best results 87-93 or the 93-91? Also how does the computer sense the difference in the octane level?

04 SC Sierra 5.3L- 40 series Flowmaster w/ 3.73's and limited slip from the factory, 2/4 drop & 20's--- Nelson 93 Octane Tune
I got the 93 hot tune and absolutely love it. It will yield you the most power gains and get you at least the gas mileage you got before. I can hammer it all day and still get at least the same as I did before! What other mods have you done?
