Low mount turbo control

[Log lugger]

Ah yes cm870 07 379 still has all it's working egr components with new egr cooler piping all recently removed and cleaned .all new sensors and holset turbo.getting the chuffing and black smoke until fuel pedal backed off a little then can go again usually happens around 1500 rpm.installed a remote air pressure gauge in the cab to read delivery pressure to the actuator it runs at 90 psi idling then 45 to 50 going along on the road and back to 90 for engine braking.i have not found anything yet in quickserve for operating pressures. But did find an old post on here between rawze and chamber pains about the subject but I believe they were dealing with the older hi mount version. I wasn't sure if the parameters were the same or not...
