I have driven the truck 2 more days now and there have been no more codes- I keep checking every time I drive it. I only got the codes on my Edge a few minutes after the install and first drive- the SES light has not been on at all. Around town I haver already picked up 1 mpg. I am about to drive 300 miles on Wednesday, all highway and steady. I will have to report back what mpg 's I get. Sounds like I will go ahead and do the egr blocker plate. THIS THING SOUNDS LIKE A BEAST NOW!!!
