well, i tried a little expiriment today, hoping to increase milage, i blocked the egr tube from flowing, and to my suprise it did set a code. i have done this on diesels with great luck, no codes and one got 100+ miles more on 30 gallons of fuel, but obviosly these are two totaly different animals, the dak seems to have some way of montering the flow, and i drove about 30 miles and didnt seem to make much of a difference in the milage, maby even a little worse, so my next thought is... i am putting a trans cooler in this weekend and no longer using the cooler in the radiator, i was thinking about getting a second egr tube, cutting it, and routing the egr through the the cooler in the radiator... any thoughts??? or am i just waisting time?

 

I would be interested to see how the truck reacts to it man...if you do decide to do it let us all know!

 

another strange idea... http://cgi.ebay.com/ebaymotors/Flex-...Q5fAccessories

im thinking of using this cooler, run the egr through the 1/2" ports, i also ordered a catch can to put on the pcv, but run the pcv through the 3/8" side and try to cool off all the air going into the intake... guess it cant really hurt anything, might as well try it

 

let us know how it goes. my buddy told me to switch over to a trans cooler. so when i get the money im getting pods and then going to switch to a trans cooler. and hes going to help out. gd luck take sum pics while ur at it.

 

I know that the 4.7 does not have to have and egr, do to the fact that mine does not have one. So there is a way to bypass it.

 

and how is that? care to share sum info?

 

I don't know how its done, but the 02 4.7 did not come with it
