I've heard of putting an Underdrive pulley on to free up some hp but where can I find one for our 2.3? And what size belt would I need after putting it on?

Your 2010 Ranger will have a 2.3l Duratec 23NS engine.
Don't confuse it with the older 2.3l Lima engine(2000 and older Rangers), when looking for a pulley.

The 2.3l Duratec 23EW engine used in Ford cars, transverse mounted, used a different(heavier) crankshaft, so pulley recommended for this one may not be good for the 23NS, can't say.

If you find one then it should also have recommended change for belt length
