Based on what others have said here, it sounds like you need an alignment. The stock specs for the '04+ have 0 camber (I think) on the front, making it understeer.

Are those COLD PSI's? This weekend, I ran 32 front, 30 rear cold, later as it got warmer, I noticed a reduced amount of grip I checked and was about 37 all around, I adjusted to 32 front hot/warm and 30 rear hot /warm and there was much more grip and I had my best run of the day.
From everything I read here that seems wrong, I should have MORE air in them, but anytime I put more the car just slides around too much.

Cold PSI is more a in the ballpark estimate. It's the hot (current) pressure that really matters, but that is more or less the cold pressure in a single lap autocross stuff. The last autocross had big temp/sunshine change during the day, which probably caused the pressures to change more than usual. There is a reason why the really serious guys do record keeping and check their pressures when they're lined up.
