as some of you know, i have been playen with some things to see if i can affect the milage for the better, and possibly gain some power along the way, first i tried to plug the egr, but it set a code, next i am going to try to route the egr pipe to the front of the truck, through a cooler, then back to the intake, i am also going to install a catch can on the pcv line and also route it through a cooler before going back to the intake, i also installed the 180 t-stat, i'm removing the trans cooler from the radiator and installing its own cooler out front, installing true duals with a dxnomax x-pipe muffler, i want to extend the CAI and enlarge the hole in the inner fender and hopefully instal the filter inside the fender, as well as wrap the cai or change it over to pvc, and removing the breather line from the cai and installing a filter on the valve cover, i have also been toying with the idea of trying to run a metered amount of propane/cng into the intake while crusing, as i have about 500 gallons of propane for free, any thoughts? and if anyone else has any reasonable/doable ideas, i may be willing to guinea pig them for ya

 

I'm gonna be following this closely, since I'd like to gain a little more mileage if possible. I'm really interested in the catch can and true duals since I'm thinking those might be coming up sometime in the semi-near future.

 

Where is the EGR on the 4.7l? Im sure mine has never been swapped out and for 50 bucks it would probably be worth it for me to do it.

Im definetly doing a catch can on mine .... My exhaust tips are black within a couple weeks from the oil blow by.

For the propane, the only thing I could think of is to hook it up like a nitrous system to the fuel rail so that each cylinder gets an even amount. Im not to sure I would run it all the time though .... Keep us posted though!

 

not sure on the 05-07 but i think they are in the same place as the 08+ which is on the very back of the driver side cylinder head

 

It looks like a metal cylinder, correct?

 

should look something like this

Thanks dodgetrucker! Ill be finding where mine is to replace it.

 

How do you know it needs to be replaced rengnath?

 

Im going to pull it off and look at it, and probably will replace it. The truck has 105k on it and probably has never been replaced. Some people have them fail at 50k and get a CEL because they get so dirty inside.

 

run 185 75 16 tires, big *** exhaust bigger as possible straight pipe or cut out with longtubes headers.very dirty stock air filter air raid TB reducer H PIPE as close as possible to headers. skid plate if bodylift is used for air flow under truck.
