    I have a 99 W900B with a 3406E that has no power. I have checked the CAC and found leaks. I replaced it and seems better but still no guts. What can I do?

    check the fuel pressure at the secondary filter should be between 75-90 lbs depending on rpm. Also try pinching the wastegate line on the turbo an see if it improves the power. And take the intake off the turbo an see if the turbine can be wiggled. up and down is ok in and out means its worn out

    How much boost are you getting? Has it thrown any codes? Also check around the exhaust manifold real close for cracks or leaks. Let us know if u figure out anything I'm chasing the same kind of problem on my E
