So just to make things clear to all, your saying you have made the exhaust 3" from the turbo back? Is that with a CAT?

If you didn't touch anything up the top, I'm wondering if all gaskets are still in place. This is strange.

Strange, I'm at a loss to explain, but it sounds like a blockage somewhere.

Did you accidentally detach the vaccuum pipe to the turbo actuator (sits above the turbo). This would cause low power and maybe the smoke too if you have a basic power up chip?

Did you do any other modification at or around the same time?

I had already asked if anything up top had been touched and came back he has done nothing to engine.
