Your desire for better turbo response without wanting an increase in peak boost or lose the stock ecu controlled boost would be best matched to the SMBC. Turbo will spool faster but ecu will continue to control peak boost. No need for a MBC+A with that setup as the target objective is different. The +A is only for a MBC installed between the BPC and the WGA bypassing the stock BPC. MBC's react late in colder weather causing overshoots wich then requires one to turn down the boost to compensate, that is where the +A comes in to "prime" the line with air so you can run closer to the limit without experiencing fuel cuts due to overshoots. The +A also allows you to sustain boost longer at higher rpms due to the downstream of the IC pressure tap for MBC pressure. So 2 benefits of that, but your objective would be best served by a SMBC. Both products are on MPPerformance's website. MBC+A is under the NG900 page where as the SMBC is under the 9-3 page.
