well... in boosted applications, you are forcing more air/fuel into the cylinder, the higher the compression, the more chance of spontaneous pre-spark detonation of the mixture. that = bad. so you need to run higher octane fuels to supress that.

i think the aleros v6 is 9.5:1 ... my rex pushing 12.4 psi stock is 8.4:1 ... ive increased it to 14.5 with no knock.
