gotta question about turbo engines and fuel..
will i have any really bad negative effects on my engine if i use eighty nine octane fuel instead of premium? ive been using that for the past two weeks..

If you hit high boost with low octane it can cause your engine to ping or knock. It could destroy it. You probably already had some knocking which your knock sensor detected. If so then your engine computer has already retarded your timing, which causes you to lose power.

89's not all that low, is it?

we just learned octane numbers in intro-o-chem about 2 weeks ago. it's a ratio of how well it burns compared to a mixture of n-octane(O.N. 100) and hexane(O.N 0). whatever percentage of n-octane in hexane equals the burnability of the gas is the octane number.
