I've been running 87 in my 95 GTP with the 3.4L DOHC, according to the manual this is ok, but if I switch to an 89 or higher am I going to notice a difference? Should I consider bumping it up if I start modding the engine, with say a CAI or FWI? And finaly, aside from effecting my wallet slightly can it hurt to to play around with the different octanes?

Go with what the manual says and the 87 octane. But it wouldn't hurt to experiment either. Try the midgrade and see how the driveability is. Run a check of mileage. My son has an '02 Olds Alero GL2 with the regular 3.4L V6. He claims his gas mileage improved with mid-grade and refuses to use regular.
