I swapped a b18c jdm in my civic but i put an aftermarket bbk single stage intake manifold on the motor im thinkin of gettin a p72 but im not sure that it would help due to the fact that the aftermarket intake manifold may not have secondary butterflies whicha p72 would initiate at 5800 rpm, should i still go with the p72 over the p2t or is it a waste?
 
p72 is the ecu for your motor, so technically it would run better with that.. but may throw a code for the secondary butterfly
 
i dont think theres a code for that
 
alrite ill proly go with the p72 then u think id lose much hp without the secondary butterflies, considering te aftermarket intake is better than the stock one?
