Good news,

I received word back from the shop today that the car is fixed. The final thing to be swapped was the injectors... apparently, the EV 14 injectors have a track history of issues -- anything from the pins falling out, to o-ring issues, etc...

So, I sent them my stock injectors and they installed them on Tuesday. Tony then put the car on the dyno and spent an hour or two tweaking the tune to work with the factory injectors (not a stretch since my 61mm pulley only makes ~19 PSI).

I will pick it up with a clean bill of health, and be able to sell it to the next owner with a clear conscience.

Moral of the story -- "Bosch, or walk home" only applies to the CPS.
