    Just changed the imap sensor and the delta p sensor you think I need to change the exhaust gas pressure sensor also? I had peterbilt clean my dpf filter they kind of screwed me I asked to get baked but they misunderstood and only did the pneumatic air cleaning
    My fuel been down I have a 19 pete 389 running a reefer 4.8 to 5.3 mpg been my average what else you think i need to do to my truck?

    Ever since I changed the downpipe (flexipipe) from my turbo cause it was cracked and changed all my drive tires my fuel mileage just dropped

    Cleaning the carbon and ports to the sensor is more important than just replacing the sensor itself. Shoving brand new sensor in a nasty port is a waste of money IMO.

    New drives have more rolling resistance and can lower milleage slightly, especially big tall lugs. Make sure all your tires are aired as hard as possible.

    I just had the overhead on my X15 done. According to the Cummins I took it to ( Normal, Illinois) they recommend between 100-150k for the first time to get it done. It was $350 out the door. Not bad.
     
    nunofreddy and Midwest Trucker Thank this.

    I'm only at 94k. But was in the area and they had no wait so went ahead and got it done.

    Yeah for sure. In and out is priceless. Did they happen to say if anything needed adjusted? I have one with 250k miles that I hadn’t done anything yet and a few in that 60 to 120k mark.
     
    JonJon78 Thanks this.
