Even with gas pedal all the way down on very small uphills my turbo boost is not going more then 10-12 PSI. start losing power even i am bobtail. check all the turbo related leaks , got new clutch also. replaced another turbo. but still same problem. Anybody can suggest me what can be wrong??

    Plugged fuel filter? Turbo boost sensor? Loose fuel line, sucking air? Any bubbles in fuel tanks?Plugged vents on fuel Tanks?Air filters? Mufflers plugged? Are you sure cac isn’t leaking? 3 yrs old or more, maybe leaking. Some simple things to check.Anything more than that, need a real Mechanic, Cac is suspect. They crack along the hot turbo side often all the way down where fins meet header.

    Spyder, I do have loss of power on high gears. New turbo, replaced ECM with new software, new boost sensor, injectors replaced, overhead done, checked for cracked cac and No boost leaks, new fuel lines, new fuel check valve and temp intake sensor. Turbo boost is 25-30 psi. Still same, loss of power. I am running out of ideas. Every advice is appreciated.

    I have a 2009 freightliner, I get hesitation in 1-3 at times like when your battery is drained and your trying to turn it over. Also rough idle when parked, power loss comes and goes , also check engine lights.
