Even with my Gutsram intake I put more air and fuel into the front cylinders because the blower is set forward. That's why it's essential (in my view) to tune by port as well as by hat injectors. Talk to the manufacturer about your options and what will work best with your BDS intake. They should know and be willing to work with you on it.
