Lack of power/new noise.

ok so about 4 months ago i cleaned my EGR valve and it was pretty bad, put new o rings gasket and got it looking like new. reinstalled didnt help with my lack of power problem. no smoke under regular driving conditions that i can tell it seems to run better since my oil cooler was replaced but still doesnt have any balls when pulling 7k. so what im wondering is is there a way to check the egr valve to make sure its working right? id love to delete the thing but dont want to void my shiny new ESP. any other things to look at? Maybe my turbo?? i do alot of idling and the past couple of days ive noticed like a squeal(may not be the best way to describe it) when i give it a little throttle after idling most of the day. not sure where its comming from under the hood havent been able to have someone listen for it while i throttle it. and cant recreate it once i get home or first thing in the morning just after extended idling. all i can think of is maybe bearing in the turbo????

just thought i would add the truck only has 60,000 miles on it, and that ive never seen more than 12MPG even on a 1,200 mile road trip all highway unloaded.

These trucks do not like to idle, do you run any centane boost in the fuel and you need to drive it like you stole it to keep things clean. I would think your turbo is messed up and the unison ring may be frozen

everyday after idling i run it like hell to work the turbo out get it up to just under 30(thats as high as i can get it dont know if it should get higher) i dont run a centane booster it would be kind of a pain in the *** to do cause i run a 100 gal. aux tank to fill up equipment. but what would you recomend i might just have to put a valve and start running it one tank at a time instead of constant gravity feed.
