fuel mileage after EGR Delete?

[acleadingham]

Hi Im a newbie but i have a question im hoping to get answered.I recently done an egr cooler delete on my 04 350 SRW 4x4 it always got a consistent 17.5 mpg but since i deleted the cooler it has dropped to 10-12 mpg. i was told it would in crease the mileage not kill it. at these fuel prices it took the fun out of driving my truck .This is my 1st diesel and really like it when i hook on to my horse trailer there is no comparison to a gas.Is this normal or is there something else i need to do to help get my mileage back any help or suggestions would greatly be appreciated.

OK what does the egr do? it is the introduction of inert gas into the combustion chamber, reason is to cool the combustion chamber to reduce N.O.X. inert gas takes up space in the combustion chamber.if you remove this inert gas you have to replace it with something==more air more fuel and more temp.lower m.p.g. if it makes you feel better my 03 experienced same thing. i hope this helps you.

I THINK IN ALL THE YEARS IVE DONE THIS I CAN ONLY THINK OF 1 O3 I DID THE EGR COOLER ON CAUSE IT WAS LEAKING COOLANT IN EXHAUST.THEM ROUND COOLERS HARDLY EVER BUST. THE REASON THEY WENT TO SQUARE ONES WAS BECAUSE THE ROUND ONES ARE NOT AS EFFICIENT AT COOLING EGR GASSES.

AS FOR TUNERS AND STUFF ILL LEAVE THAT TO THE EXPERTS ON HERE I'M NOT KNOWLEDGEABLE AS SOME OF THESE FELLOWS ON HERE ABOUT THEM SORRY

I'M PUTTING MINE BACK ON FOR TWO REASONS. HERE IN PA AND NJ THEY ARE RANDOMLY PULLING OVER DIESEL TRUCKS AND CHECKING THEM FOR EMISSIONS COMPLIANCE THE STATE POLICE THAT IS AND THEY HAVE ALL TOOLS THEY NEED TO CHECK TRUCKS. AND GUESS WHAT. IF THEY ARE NOT ON IT IS 10,000 DOLLAR FINE PER OFFENSE MEANING NO CAT WHAMMY, NO EGR WHAMMY, TUNE WHAMMY, THAT IS 30,000 RIGHT THERE AND THE STATE AND FEDS SPLIT IT.

I can see a fine for no cat, or EGR delete, however how can they fine you for running a tuner? I'm just curious about this, not trying to argue with you.

SURE THE TUNER SAYS FOR OFF ROAD USE. CORRECT OR IS IT A TUNER TO GAIN MILEAGE IN THERE EYES IT DOESN'T MATTER THIS IS WHY. FORD MAKES A CALIBRATION FOR THE TRUCK AND THEN THE FEDS LOOK AT IT AND DETERMINE IF IT MEETS CARBS STANDARDS. YOU CHANGE THAT AND YOU HAVE MESSED WITH EMISSIONS. WHY ARE NOT ALLOWED TO PROGRAM THEM UNLESS TSB PERTAINS TO PROBLEM.

So do they just visually inspect for a tuner, or do they actually scan the vehicle with a program and see if it's been tuned? I see what your saying, this is just shocking....

This is why I won't delete mine...
