    Lack of power

    What does the EGR do exactly? Does it control the amount of Exhaust gas recirculated? Will not the combustion temperatures rise if removed? Do you need reduce exhaust back pressure and improve airflow before messing with this? Sorry for all the questions just trying to understand how...

    What is a straight pipe?

    when you guys talk about your trucks have straight pipes do you mean you have removed the muffler and particulate filter? My diesel mechanic neighbor suggested I remove these to improve airflow, reduce egr's and get better mileage. We don't have green police like California so I am not...

    '03 250 PSD Rough Running Until Warm?

    I also experience rough idling when the truck first starts with a cold engine, along with lack of power if I don't let the tranny temp come into range. my truck does not idle near 1100 though, it usually drops to 650-750 after a few minutes of running.

    Question Mileage Question
