Keep in mind the ECU is operating in closed loop for both fuel (via wideband) and spark (via knock). The tuning topics of fuel injection timing and cam phasing aren't as commonly discussed here but it's unlikely there's a ton left on the table with those.

The fact that he tuned it before the changes, gives less credibility to the whole thing. If this was the case on a stock tune, I would be more prone to agree.
