That is not a "small" boost leak.

I wouldn't trust that piston anymore, at the very least it needs to come out and polish out those divots/sharp edges from the bits bouncing around and inspect the rod bearing and crank.

I would sit down with the tuner and discuss all the modifications and your expectations the car. Sounds like you had a major disconnect while going through the tuning process which lead to a faild engine. The tuner should have had safeties setup and you shouldn't have been driving like you were when it failed. This situation was completely avoidable.
