Im thinking about getting a 93 octane tune. How much of a gain would I get over 87 im on now?

American Muscle Tech Guide says
Example: a stock 2001 GT might see roughly the following results:

87 octane: 2-3 horsepower gain
91 octane: 17 horsepower gain
93 octane: 20+ horsepower gain

I'm guessing with your mods the gain would be substantial considering these facts from AM

i would be suprised to see you pick up more than 20 hp. Being na all the added octane will give you is the ability to bump the timing up a few degrees. I am no expert but thats what i would guess with my experience.

really wow I didnt think it would be that much. I was thinking it would be around 5 or 10

bumping the timing will net you more power and MPG that is if you can keep your foot out of the new powah :P
