I was thinking about going with some 28" slicks and I know its going to mess with my abs but if I don't correct it in the pcm how bad is it going to run? Will it mess with my shift points? I know the speedometer will be off. I'm only going to use these sometimes, but my other tires are 26", and I don't have a way to tune the car. It was tuned on 26" tires. Thanks for the help!

Chances are it'll think you're going slower than what you really are and may bounce off of the rev limiter in the WOT upshifts.

I don't think it will mess with your shift points. Your shift speeds will be off but your speedometer will be off by exactly the same amount.
