Probably not the right thread for this particular question Dan.
But to briefly answer your questions:
1) Just so you know, you cannot just "tune" a fuel injected, ecu based engine. Some people, for some reason not all, have some over fueling issues with some particular VTA BOV's. The ecu generally does not like loosing a heap of metered air. That is what happens every time the BOV vents. Does this make sense?
2) Same as the first part of the above answer. Generally you will have positive results to an uprated intercooler.
