Low Boost Pressure
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 care of). It all boiled down to this; I was pressurizing my turbo system and air was coming out as fast as I could put it in. I felt around and as it turns out the pedestal was not connected at all. Air was simply dumping out so after the removal of my passenger side boot, I reached in there hooked it up with the clip (which was luckily still there).
I took the truck out for a drive using a cheap boost gauge I had bought for the occasion and viola, it laid me back in my seat. Boost pressure when flooring it hit nearly 20 psi. I had recently been pulling a 25' horse trailer and while flooring it previous to the fix I only got a max of 14 psi not evenly through the gears either. The boost pressure after the fix was evenly through the gears and my truck even sounded better.
Thanks to all those who have posted on this site, this is just a small payback for all the help I received; perhaps this can save someone a lot of time and a lot of gas money. My mpg in the truck never hit above 13 previous to this and I have checked it on every fill-up. I am interested to see what I get now; I will try to post my new mpg after I take another long trip.
Have a great day and don't forget to vote when the time comes.
