Wow, your post is quite difficult to read. What year is your truck and what turbo did you install? Just as an FYI, most folks experience an exhaust leak at the up-pipe or y-pipe when reinstalling a turbo on the 6.0L. Check for soot on or near the firewall and also check your intercooler boots to ensure they are on good and snug.

Sorry its a 03 6.0 stock rebuilt turbo all hoses are good n tight will check ypipe tonight I know it tight at turbo can take ypipe out with turbo still in or take turbo out then ypipe come s out

No, you need to remove the turbo to get it out. It won't clear the firewall/engine block to remove it from below. But why would you want to remove it? You wouldn't want to pull the y-pipe out unless you knew it was blown out. Check the connections. Most folks have the best success by loosening the y-pipe from the exhaust manifolds, tightening the y-pipe to turbo flange, and then re-tightening the y-pipe to exhaust manifold bolts.

Was this rebuilt turbo used? That y-pipe needs to seat properly into the exhaust housing. With a different turbo, like previously said sometimes you need to loosen the y-pipe at the manifold to make sure it's seated correctly.

If your pipe is leaking or loose you'll be able to see soot coming out the top of the motor in front of the fire wall. If you were not careful and bumped the pipe during the installation of the new turbo you could have cracked the expansion section of the pipe, this can cause low performance, laggy response, high egts, and lots of smoke.

Also do you notice any exhaust smell or soot inside the cab? I know when mine when I had soot rolling in through the vents and you could smell the exhaust in the cab.

check y-pipe last night seen a little smoke from that area and remove turbo to check the y-pipe looks good and it look good at the turbo should I put turbo back in and readjust pipe and tighten trying to to get this pos running today thanks for the help

If you have the time I would take the pipe off and check the expansion joints for holes. Mine was cracked and there was no way I'd ever be able to see if from just looking back there with the turbo off.
