Default 95 octane tune

How much hp do you guys feel can be had from using 95 octane and tunning it to run on that gas(turning up the timing from stock). The car is a 06 with long tube headers, no cats, ghl exhaust and a ram air intake. No tune yet just turned off the O2's. It is running on the tune designed for 89 octane. I know i will get 10-15hp just from tuning the mods i have but I was wondering what the extra 6 octane points could do for me.

With a bump up in compression you would see some good gains, but the basic stock LS based motor will probably only gain a few HP from being able to bump the timeing up a tad, and I suggest always going with a safe 93 octaine tune to avoid detonation. On our dragster motors we run 15-15 1/2: 1 and run 32-36 degrees. And we run Methanol. The rest of the mods should do you well!

yea i know the compression would help but i figured if i was going to open the engine it would be for a cam. I was just trying to make power that was easily reversible if i had a engine problem without going the nitrous path.
