All 2.5L Owners

I was wondering what other 2.5l owners have done to there engines to get a little more power out of them.
Over the past few months, I've added replaced a few things and have saw a definite increase in power. When I first bought my Jeep, it was very sad. I've repleced the air filter, fuel pump, fuel filter, oil sending unit, rotor button, plugs, plug wires, and exhaust (off roading mishap), and the engine has livened up a good bit, but still isn't exactly where I'd like it to be.
It would be great to get to know what others have done to make more power, so we all don't have to live with such an underpowered vehicle.
So, any suggestions?

electric fan helps the throttle body spacer is a waste of time. Highflow cat. helps to. I plan on swapping in 4.88's before spring that should help quite a bit.

I never thought about an electric fan, that's a good idea. How much does one of those cost?
Anyone else?

TBS is better suited as a paperweight.

get creative with the mounting...i.e: zip ties through the radiator fins, metal straps that screw to the cowl and to the fan, duct tape, bubble gum, you may have to cut down your cowl to make room, or just remove your cowl and mount it right up against the radiator.

4.88s made a world of difference for me.
