2011 f550 Turbo problem
Hey guys. Im working on a buddies f550 and just took it for a test drive and when i stepped on the go pedal it was doggy till around 1500 rpm (only gaining 5psi boost) then it got a kick in the *** and took off and finally started gaining boost. Also it had a hi pitched sound like a jake brake or something was engaged but the truck doesn't have one?! This doesn't seem normal to a Cummins guy. Thanks in advance!
