Those 2 codes are VERY common if you have any kind of programmer.

I'm still getting the underboost code even with a new turbo and I haven't reinstalled the power puck since I got the truck back. So I don't think the puck is causing my problems.

 

I'm going to cut the cat off tomorrow and take it up to an exhuast shop and get them to install a straight pipe. Will it hurt to drive it a little ways with not only a few feet of pipe behind the turbo? I would just let the exhaust shop cut it off, but its illegal for them to do it in Texas, but they can put on the new pipe if I bring it with no cat to start with.

 

I cut my cat off today and had a straight pipe put in. WOW. That has been my problem all along. When I got the cat off the insides were shredded and so I dumped it out onto the garage floor. I found the turbine wheel with all of the blades still intact inside the cat. Has anyone ever seen anything like this? My truck runs awesome now. It must have been like this since I bought it and it has never run like it should. Thanks for all the tips and ideas hopefully I won't need anymore for a while.

If I knew how to upload photos I would show you a picture of the turbo part that I found in the cat. I thought it was unbelievable.

 

as long as the photo's arent too big you can just upload them when you hit the post reply button. . .if you need to resize them I can do that for ya and post them up.

 

As soon as I get home I'll try getting the pic up, its unbelieveable.
