If I set my cruise control and have a little self control I average 18-19 mpg before the deletes I was only getting around 14-15 before. Also I have not heard the fuel knock on mine for a long time, not sure what made it quit but I think it actually was the egr delete that made it quit not for sure though
I am getting a consistent 17 MPG with mine 75% town driving and 25% towing between 5k and 17k. I have been running the deletes for about 8k. I heard the Knock for a little while but since i have been running the MP-8 Cranked i havent noticed it. I dont have the AX flash either.
my truck is stock other then egr delete and dpf delete. before best i could get was 15.8
with dpf gone i was getting 16.4 with both done im seeing 18.8 and 19.2 consistently. Need to get the mp8 and see if that helps out even more
My milage has gone up since the egr delete, It also made my overhead further off. I think the milage goes up form how much less it smokes. Mine would smoke just cruisin down the road with no load on it, now it doesn't. So that fuel is gettin burned to push the truck not just out the tail pipe!
i ran a couple of times just before the egr and dpf fell off, 75mph was getting 450miles/tank, with about 20k on the truck, now seem to be getting 620 or better depending on wind. afe megga II and edge on level 2. this works out to about 14.7 prior and 20.9 now. well worth the time and money to me, i drive alot for work and won't take that long to pay off the extras with fuel this high.:thumbsup
