Angry 9 MPG... Pathetic

So heres the deal, had my truck for about a year now, and have always gotten terrible mileage.
normally between 230-280 MAX a tank, sometimes 180...

My truck was stock completely when I got it, added a 4 inch cat back exhaust, deleted the cat, and got an SCT Livewire.
Still ****.

Recently blew my heads apart, 4 valves got stuck open and bent the rocker arms.
So just spent $7690 to get it back.
Brand new heads, brand new gaskets, ARP headstuds, 155 RCD injectors, EGR blockoff with a bulletproof EGR, BullyDog CAI, SCT Livewire with Custom tunes from dfuser, 4.5 inch lift on some 35's, and also have a 3.5 inch downpipe sitting in the box waiting to be put on.
Anybody have any suggestions, tried ONE time driving normally and it didnt help at all.

Also on these tunes, even the preset tunes from the SCT, and even before I had the injectors, my EGT's were always spiking 1600, not sure if that helps but just an FYI...

EGT's are way high. How are your up pipes and IC boots.

The other thing is DFuser's tunes are know to run hot as hell

I had his race tune on a truck a couple years ago. I could peg a 2k degree pyro with stock injectors

Check your FICM as well, could cause terrible fuel mileage.

Yea, something is being over looked here.

Can you list the maintenance and miles on the truck?

Do you have tunes for the 155cc inj?
