Tuned Port is a type of Multi port fuel injection. Any fuel injection system having a injector for each cylinder is multi port. Also welcome to the forum.

A question regarding MPFI... What's the difference between it and Sequential Fuel Injection (or SFI)?

mulit port is batch fire, for example if one of the injectors on the odd bank of the engine fires, all the injectors for that bank fire. Sequential fuel injection each injector fires seperetly when it is told to.
