Bad mpg's Replaced bad ebps tube

Mpg's have been getting worse. Checked ebps tube and seen it was broke off at exhaust manifold. I replaced that and am getting decent psi readings on AE and also put in dieselsite's 203* thermostat and mpg's are still no better and truck still smokes a lot, really bad when cold. Doesn't matter what tune I'm in also. I assumed a good ebps tube would give me 2 mpg's better but not the case. Fuel filter is new. What else to check for bad mpg's?

It does always seem sluggish. No matter what tune I'm in also. Obviously my modified stock tune is going to be less power, but for what mods I'm running it seems it should be better. Having PHP tunes, Bill is supposed to be known for non-smokey tunes. My numbers on AE all seem to be OK, but I really don't have anything to compare against. I mean all sensors appear to be working, but I really don't know what they should be.

15. Not real terrible but I've been used to 18-21. I can't understand why I wouldn't see any improvement after a bad ebps tube and a dieselsite stat??

Pretty new. About 4k miles on it its a big AFE II conical filter. More grey/white smoke. But it will definitely roll the coal when getting on the highway. I'm thinking I'm prolly gonna have to drop the fuel tank. IDK.

Their could be debris in the tank causing the fuel transfer pump to work harder. I believe their is a check valve for the fuel and it could be bleeding down. Let it sit over night and make sure the fuel bowel is full. Pull the regulator off and make sure the little screen isn't plugged. Another idea maybe an oring on an injector leaking causing fuel to dump into the cyls excessively. When u change ur oil next or pull the dip stick and see if the oil is thinned out and smells like fuel.

You fixed the ebps tube. Is the sensor itself good? Just a thought.

Yes. I hooked up AE and am reading 14.8 at idle 14.6 on MAP at idle. Which is 1 atmosphere, and at WOT I'm at 38.6 bp and 36.1 on boost. Minus the 14.6-8 respectively for actual pressures. So I'm seeing roughly 24psi boost on a factory turbo. FWIW I'm seeing 800psi/idle and 3300psi/wot on hpop .
