Loss of power, high EGT
 

I've owned this truck for a while and have noticed a loss in HP over the last year while the exhaust temps averaging around 800 just going down the road with little to 10 psi of boost.
I have not seen any temp over 1200 degrees while towing but can't figure while I am running so high normally. I recall it normally running around 600 degrees on pyro while just driving but am wondering if I am getting a poor spray pattern on an injector or dripping injector. I am running the Superchip @ tow/haul under weight setting and I have not noticed any significant black smoke in mirror. Any suggestions? Thanks!

Fuel mileage has also dropped but not all the time, I used to get 20-22 mpg now more like 17-18 mpg, sometimes I get 19mpg. Fuel pressure is 16-18psi @ idle and 8-10psi WOT. Little difference I know but I notice w/ fuel @ $4.00+ a gallon. Have not changed the fuel filter in 15k fyi may contribute but doesn't explaing high EGT. Any help is greatly appreciated.

Might have a boost leak. Makes higher egts and could lower fuel economy. Change that filter first

Replaced fuel filter, ran one tank and have constant boost pressure with no bleeding, fuel mileage is the same, crappy! Thanks wyodiesel92, I had a buddy verify and help make sure that was good. I am thinking of having a pop test done and see where I am at on the injectors. Any other thoughts?

That'd be my nextstep pop testing injectors
