Best off yanking the smoke switch out and build for power... The smoke switch causes the VP44 to go into full retard timing. Performance wise it kills the horsepower. Trust after playing with it for a few month I did the same thing yanked it out because it doesn't do the truck any good to flood the cylinders with a bunch of fuel it can't burn. Tell you the truth with the price of fuel being what it is your willing to waste fuel for show...

As for the P0236 code its "Boost too high too long"... In other words the ECM see the MAP sensor is high too long. If you going to operate the smoke switch you only want it on for no longer than a few seconds (just like typical boost) other than that the ECM toss the P0236 code.

As with the high volt codes double check your driver side ground. As for the low volt on the map sensor I think it could of been unplugged or loose...
