bm uses existing fpr base ( a moded OEM fpr) AEM is a complete replacement, it can handle more psi and it looks sexyer

If I understand correctly the B&M will not allow you to decrease the fuel pressure as it uses the oem fpr. The AEM will allow you to drop fuel pressure if your static pressure is too high ie. if you are using a high pressure fuel pump. This was the case for me. The Walbro 255 hp bumped up my fuel pressure so much I was getting a running too rich code (172).
