low boost

  1. 6.0L Problems Forum
    Hello all, Recently removed my turbo to clean vanes and unison ring from P0299 pow boost. Truck would start with no turbo spool until reaching a certain RPM or would eventually after leaving at idle for a bit... VGT would stick at 85% until then. I assume the heat (and maybe oil pressure?)...
  2. 99-03 7.3L Powerstroke Problems
    Hello, I'm new to the forum and new to diesels, so pardon my ignorance. I've recently purchased an E450 shuttle bus and am converting it into a RV style vehicle. I just got a scan gauge 2 to monitor some more parameters on the engine. After calibrating the boost reading, I took it for a spin to...
  3. 6.4 Motor Problems
    Weird VGT problem with my 08 6.4, the VGT cycle is almost constantly read at 95, which I presume is closed as the truck has the standard symptoms of being laggy from a start, blowing out a ton of soot, and the boost not kicking in until the larger turbo spools. I have replaced the ebp sensor and...
  4. 99-03 7.3 Motor Problems
    I'll try to make this a comprehensive as possible without writing a novel. - Bear with a noob please. 2002 F250 - 4x4 auto CCSB. Bought almost a month ago with ~250k miles. Pulled about as strong to other 7.3 - maybe a bit more sluggish in higher RPMs. Bought torque pro - saw boost (map & the...
  5. 6.4L Problems Forum
    Hey guys this is my first post, so I have owned this F250 for a month now, and have had a few issues i'd really like to fix. It has a Code for Cylinder 2 Contribution/ Balance (P0266). It misfires when cold sometimes but runs ok once warm. But a hour ago I was helping my friend do clutch on...
  6. 6.0 Motor problems
    New to forums, Need help with 2007 F250 6.0 that starts up hard and has low to none boost. The turbo makes a very loud constant pinging, goes away when we unplug the turbo solenoid, so we do know that it is coming from the turbo. We also just cleaned the inside of the turbo and replaced the...

  8. 99-03 7.3 Motor Problems
    Ok so I'm new to diesels. I'm not a mechanic I'm a landscaper. I bought a used 2000 F350 7.3 auto dump body DRW 4x4. When I bought the truck I just needed it for the dumping and for plowing. So I never really felt what actual "boost" in a 7.3 feels like. Anyways down the line I has a major...
  9. 6.0 Motor problems
    I have a 2005 f-250 6.0 that I just recently bulletproofed. It had these same performance issues before & after being bulletproofed. I guess I should back up & say it was a repossession & I only drove it 2 miles before bulletproofing it so I don't know much about the history. The truck has ARP...
  10. 6.0L Problems Forum
    My 04 is idling real rough and is only pushing 26psi of boost max. At first it sounded like it was misfiring so I replaced all the injectors and it is definitely running better but still having the same issues. When I put my sct in performance mode and push the pedal more than halfway it bogs...
  11. 6.0 Motor problems
    Hi guys, if anyone could help me I would appreciate it greatly. It all started when the little wrench light started coming on after driving a while. (05 f350) I took it to the dealer and had them read it and of course it was the oil cooler. So I bought all the parts needed to do the job and went...

  13. 94-98 7.3 Motor Problems
    Seems like a loss of Boost/Power happened within the last three weeks. My 97 has 3" downpipe, 4" exhaust, with diy cold air intake and TS chip with just over 240,000 miles. This setup has been running great for the last three years, but lately it's been doggin. Boost develops slower than...

  17. 99-03 7.3L Powerstroke Problems
    I bought my Early 99 California model F350 a few months ago. It always felt pretty gutless and I assumed it was a turbo issue; after checking countless problems such as EBP Exhaust Back Pressure Sensor (which did need cleaned by the way), map sensor, replaced ball joints (which also needed taken...
