Paccar Mx 13 Loss Of Powerfaq - Last week my boost started suddenly dropping. then would pick back up again. Got the truck to the shop. Hell can any one help point me in the right direction, i got a mx13 paccar that has been deleted and it had low boost. We have checked the charge air system it does not have. The other day it started this: Boost will fluctuate inexplicably. So we might be driving along loaded and suddenly the power drops. Notice the boost gauge shows a boost. I lose all power climbing hills of all sizes (don’t feel it as bad on flat land) and once i’m back into 13th gear and feather the accelerator, i can feel the miss fire feeling go away.
