Not with my truck though. Pretty sure it doesnt have the power. Anybody know of hand what kind of boost the stock turbo should be producing?

See thats what I thought. I can only get about 10-12 and it is not running right. Also vibration starts about 4th gear and gets worse until 6th is steady drone and vibration. Driving me nuts. Just dropped new DD clutch in(man is it noisy) and vibration still there.

That's why I went with the Auto. I tow a heavy 5th and so far it has been perfect. I heard problems with the Manual Dual Mass flywheel and such.. didn't want that headache. My old 2001 5600 6 speed had problems too..

So any ideas? Cant think of anything that would cause low power, low boost, and vibration unless I have more than one issue.

I will check that when i get back. The issue was there before i changed clutch. The old factory clutch was slipping bad and throwout bearing was going. I was hoping that was problem with vibration. Needed clutch anyways

I think problems arise from emissions equipment, probably need turbo cleaned or somthing. Delete whatever you can in your area seems to be the best thing you can do with newer trucks.

Didnt even think about that was just assuming it was deleted. My buddies truck the
ebrake was sticking . We just did the deletes yesterday with smarty jr. Thanks to MIGHTY DIESEL

So that could be a prob with yours also. what do you have dont to your truck ?

put it in your sig so we all know and everyone can help out a little more

On the vibration do you have a carrier bearing on your driveline? Is it good? Have you checked ujoints ect.? My truck likes to eat ujoints
