a wiring issue maybe?? These things are also bad to have faulty under valve cover harnesses. Also, bear in mind...the turbo only responds (mechanically) to the amount of exhaust flow which is a result of adding more fuel. Example...when you mash the gas pedal more fuel is added which makes more exhaust pressure which spools up the turbo which creates boost on the turbo intake side. Boost is a direct result of exhaust pressure created by the engine. The turbo can kick in so to speak unless the motor is producing a response to a greater load. All the turbo can do is respond to that load. Now, on the other hand..if the exhaust back pressure valve is trying to engage at highway speeds (which it should not do once the engine is warm) it would seem like power is down, you would hear a noisy that could be mistaken as the turbo working harder and could also cause a staling problem if it was trying to operate at the wrong time. The computer may see that as a serious issue and try to defuel or stall. Not sure if any of that helps but hopefully it may. Also, as a side note...i did get a bad cps at autozone a few years back...truck died and would not start...i replaced the sensor and drove it home. Next day it stalled but restarted. Did that for several weeks until i replaced the cps again and it has been fine since.
