I guess the code was there before...
I'd look hard on the boost side.
Said that your only doin 60moh and start to smoke as soon as you work it sounds like there is the problem, lack of air for proper combustion.
Boost leak is easy to diagnose in the field. Takin off the pipe between air filter and turbo, exposing the turbo inlet. Have the engine idle, take a piece of STIFF cardboard or anything else that's nice and flat. Put the cardboard onto the turbo inlet, it will starve the engine within 2 seconds from air. This will produce a vacuum in the whole intake system. With the engine starved and off you'll hear any small leak taking in air and the cardboard will fall off. Repeat if your hear a leak but can't pinpoint it the first time.
Edit: if the engine does not starve - you have a massive leak.
