I know the OP said his indy changed the AOS, but I would double check it myself AND the j-tube if he did NOT change. Especially if indy is not overly familiar w/ P-cars. If the white smoke were just generally coming from the car, it could easily be a number of things. Coming from the exhaust though narrows it down. Anyhow, as I said above, check the j-tube - it connects from the AOS to the throttle body (shiny black tube shown here - varies somewhat based on MY though):



Squeeze the connector at end by the throttle body and see if oil is pooling in there. A light misting is all that should be present. If it's more, cleaned it out or change ASAP.

Also, if the AOS was bad, oil (more than the emissions misting) was getting sucked thru the throttle body into the cylinders. That means, assuming TB was not cleaned out, there is still plenty left in the TB and under hard acceleration, the remnants are still getting thru to cylinders. Pull and clean the TB ASAP ...
