  1. have you checked your fuel pressure? it is commonly over looked at shops, it should be running 59 at idle 80 at full throttle, the electronic motors like to spin the nylon gear away from the pump shaft. is it a vgt turbo? is there a large position sensor on the side of the turbo?
  2. 6 eecu's throws up a flag for me as a mack technician, for what reason were they replaced? sluggishness could be from low fuel pressure, an incorrect engine file, or eup codes not programmed in, horse power upgrades can be done, but they are EXPENSIVE and you can normally only go 50 horse higher. they are not bad trucks, the egr and vgt systems can have common issues, but are warranty covered for 5 yrs or 300,000 miles so are engine ecu's and vehicle ecu's. the AI motors IEGR and CEGR are MUCH more reliable than the new MP7 and MP8 motors.
  3. i'm interested in knowing how many people on here drive the new Macks? starting with the mp7 half breed?
  4. in my opinion vmac 4 is a joke, its basically recoded volvo software, in a volvo eecu, vecu and cluster module.
  5. hello every one, well as the title states i'm not a truck owner, but i am a Mack technician, i'm an electronics specialist and problem solver, i deal mostly with the vmac systems especially vmac4. i have discovered and repaired a couple issues that mack/volvo has had. i have a website that holds information on some of the things i do. ill be glad to help in any way i can.
