You just have the K&N drop in? Might be worth it to consider a CAI and really let it breathe then a tuner would definitely help maximize those first two mods.

we have vendors here in the forums that sell them....I went through RPMOutlet and got their stage 3 package, K&N CAI, programmer and underdrive pulley....pulley is on backorder though, total package deal was around 800, but they didn't charge me for the pulley so it was a little over 700 for the CAI and programmer...but here is Diablo's main page.

let me find the vendors that we have here and I'll link it....meantime shoot Diablo an email or call them, don't see why the one listed for the '03 wouldn't work.

Edit..Here's a thread talking about the '02 4.7's...maybe the Diablos won't work for the '02s

wow that mpg isn't very good. my dads gets 17 hwy or city its the same engine. how many miles do you have, I'd guess something else is wrong, maybe needs a tuneup, or a brake caliper is sticking, etc... I wouldn't bother spending hundreds of dollars to maybe pick up 1 mpg, it won't be cost effective. the TB spacers don't do anything, but with a tuner you might pick up 1 mpg or 2 at the most.
