do you think that could be because the intake system makes more noise now you dont stick your foot down as far at part throttle the air filter even a stock paper one does not restrict flow nor does a k$n give more flow than the engine demands. -- budd cochran john 316-17 ephesians 28-9 our constitution was made only for a moral and religious people. it is wholly inadequate for the government of any other. john adams i cant speak for the cummuns but a k and n air filter helped my car get 3 mpgs more other than that i really dont know off the top of my head. *** free account sponsored by secureix.com *** *** encrypt your internet usage with a free vpn account from http//www.secureix.com *** .

do you think that could be because the intake system makes more noise now you dont stick your foot down as far if he is using a k&n replacement filter there will be no increase in noise and while the complete kit does sound different than stock but if he has a diesel you probably wouldnt be able to hear it over the noise of the engine. my buddy has one on his ford full induction kit and you cant hear anything different. at part throttle the air filter even a stock paper one does not restrict flow nor does a k$n give more flow than the engine demands. all filters and intake systems restrict flow including the k&n it is just a matter of how much and if there is enough of a difference in an after market system to change performance. -- if at first you dont succeed youre not cut out for skydiving .

fair enough i guess it depends on the kit. -- if at first you dont succeed youre not cut out for skydiving and while the complete kit does sound different than stock but if he has a diesel you probably wouldnt be able to hear it over the noise of the when i replaced my stock air box with an afe cone filter the turbo noise was definately more pronounced. .

i posted this on alt.rv a few weeks ago i am towing an artic fox 29-5 13500 pounds fully loaded with a 06 dodge 3500 dieselw/ drw 3.73 rear end and a 6 spd manual transmission. the mileage varies from 8mpg temperature between 30 & 50 degrees f to 10 mpg temperature 60 to 70 degrees f at a speed of 60 to 65 mph. the truck is nearly new with 9800 miles. and got several replies suggesting that i go slower and wait until i get more miles on the motor. the electronic mpg display is up to 15% off when driving without towing. i am keeping track of the milage under different conditions and taking it back to the dealer. it appears that the inlet air temperature sensor might be bad dont know. jrb .

i have read that a bad lift pump will do this. put a fuel pressure gauge on it for a few days and see if the pressure is low or erratic. the guy who wrote about it had a brand new truck running 0-4 psi or so instead of 7 psi. he also had low power. he had the lift pump replaced and his mileage returned to normal 14-16 mpg and 10mpg loaded. i read your reply posts stating that you have a new engine due to a fuel pump. could that old bad lift pump have harmed your high pressure pump the expensive one or your injectors if your dealer cant help you try a new dealer. 6mpg is too low for a heathly engine. look to http//www.dodgetrucks.org/forums/index.php for other ideas. need all the help i can get on how to get more fuel mileage out of my 05 cummins it has about 5000 miles on a short block that the dealer had to put at 13000.. we are only getting 13mpg and when we put on the trailer we drop to 6mpg. if any of you can be of more help please teel me all you know . 3500 dually 4x4 6 speed quad cab p.s. could use a little more power to !!!!!! lets hear it thanks peter .
