You could always throw a turbo on it, that might help.

LOL, I agree with the bigger tires, if you could put the stockers back on I think you'd find a positive difference.

I have 93 2.5, 5 speed with 31s and I hold 110 easily on the highway I lose a couple k's going uphill, and she has 170;000 on her..I would check the cat, there is a flow direction on them, it could be backwards? And of course it could be just tired...Tune her up and see if that helps..
