Hey guys my 2006 LBZ CCSB 4x4 is getting 12.5mpg and 260ish miles to the tank. I’m guessing normal 26gal tank, it has 285 bfg all terrains stock wheels, egr block, injen cold air intake, resonator delete, down pipe back 4in straight pipe and I don’t drive like a bat out of hades. Was getting 15.6 before I put a new cluster in it. No visible leaks fuel head stays tight, has raptor 150 lift pump. Balance rates look great but #6 is only a little out of spec when in park when the engine is cold but drops to spec when warm. Runs great seems to have good power. No black smoke from tailpipe just a little haze you can see at night. Hazes a tad at idle when it’s warm and sits idling for an extended period of time. Pleas help I’m about to tear my hair out!

Condition of the air filter?

 

Any turbo charge air cooler boots loose?  Hoses cracked?

 

Was the new cluster programmed to the truck when installed?

Cluster was done by local stealer so I’m hoping they did. Didn’t see any hoses loose and if they were wouldn’t it dump black smoke everywhere?

air filter only has a few thousand miles on it
