id do an E-fan and change the front o2's forsure. you can get the MIL things for the rear or just wait to get a tune and tune it for the rear o2's to be delted. they just tell the computer the cats are working.
the front o2's tell the comp. how much air/fuel is in the exhuast so it can adjust i saw a 4MPG increase when i replaced my front o2's. also when i did my E-fan i think i got 1 more MPG or so.
Also if you want to DIY with tunes i have the sniper custom tuner. i made my own custom tune and put it in under 30 mins. and i can make as many diff. tunes for my truck as i want. 400 bucks and you can tune 2 ford gas cars/trucks out of the box. i love it went half in with a buddy and we both love it.
but id start with them o2's and an E-fan.

well, i am fixing to order a tune and was thinking of VMP... front O2's have been replaced and the EGR is now clean... it was completely stoped up... does anyone know if the gas saver tunes are worth the money? its getting 17.5/18 consistently now... but looking to get 20 again out of it...
