arghx7 With the D4-S we get the advantage of working with port or direct as we see fit (or do we? Does the ECU tuning software allow independent duty cycle adjustments of the different injectors?), so if chasing high flow we still have a port system if that generates more power.
But I think our current crop if tuners has a LOT of learning to do both with just NA basics and the combination injection , and I don't think most of them will take the effort required to expand their own knowledge.
