What about cleaning the MAF?

Maybe get you injectors cleaned (directly inject the cleaner into the rail, I believe or nearby). I get this done every 12-24 months and it helps a lot.

ya, go to your dealership and get an injector flush. i work at one so we had exta stuff around the shop. helped out power wise also. costs around 70.00 i think. well worth it imo.

what about an off road pipe?

I am running a bottle of lucas fuel injector cleaner in the current tank of gas and honestly I can feel a difference- a small difference mind you it might be worth the $4 to give it a try.

alright, any other suggestions guys?
its really getting annoying, like to the point of me not wanting to drive the damn thing :|

Well, you'd think clogged injectors would use less fuel, not more ...

124 miles per tank is dumping lots of extra fuel somehow. I think it's computer related. You obviously running way too rich.

Get a good diagnostic somewhere on the computer and see why its dumping fuel.
