first I ve read this from another post for edge timing

"Roughly 1 degree per 2 octane.

Level 3 (basically 91 octane tune) running 93 = +1 deg.
Level 2 (basically 87 octane tune) running 93 = +3 deg.

Level 3 running 100/101 = +5 deg. (This is for the rich guys!)

These are ideal values at sea level. At altitude, you should be able to add another degree per 2500 ft.

5000 ft. = +2 deg."

I have a 30 gallon tank, If I run 100/101 octane in 5-10 gallons in my truck mixed with 20-25 gallons of 91 octane gas how much would I be able to bump the timing on my edge evo 1.5-2.5 degrees or more?

also when I shift from 2-3 gear floored my belt churps, will it snap eventually, if so will a gatorback belt help?

 

Not sure about the top part. You'll have drag out the calculator and find out. But to be on the safe side..I'd say run your tank to the Low Fuel indicator comes on then fill it up with 100 octane.

Last question, yep, and gatorback belt will end the belt squeal.

 

sweet thanks bro, so a gotorbck belt is just typically stronger than stock and is more durible then stock right, also its an easy install right?

I've never replaced the belts before on my f150 but I believe if you can tell the difference between a screwdriver and a hammer, you should be fine installing it yourself. I've got to get me one here shortly.
