Default Degree of timing/octane??????

I'm looking for a round about figure of how many degrees I can advance timing. I'm going to a 110 octane leaded fuel, and need to know asap.

Thanks

Is your car boosted or are running N2O? Because if not 110 will do nothing for you. Besides that advancing timing only give power to certain extent and then power falls off. Oh yea leaded gas will kill your O2's and can clog the cats.

02's are cooked and all 4 are off, and I have no cats. I have 11:1 C/R. I'm running N20, and will be on 110 by default(the track), until I run out, and can fill up with 93 again, and swap back 2 my 93 tune. So, while im running on 110, I sure as hell wanna get the most out of it, at $5 a gal. lol


Thanks JD
