different ecu's for spg's?

it seems the fueling issues experienced when varying beyond stock boost levels are not easily corrected, at least ideally. however, the spg's that came stock with more hp had a tweaked apc (red box). question is, did saab reprogram the ecu closed loop fuel map at wot to account for increased boost pressure? since base boost setting is higher in stock spg than in stock turbo, and apc box was tweak for higher hp, it would make sense that the wot fuel map would need to be different. granted that the spg ecu would not be a solution to the leaning out at high rpm under full boost, but it may be closer than the stock turbo ecu. any thoughts?
