This is a throttle body EFI and still has many drawbacks of a carb. OEM's quit using throttle bodies years ago for good reason, port fuel injection is MUCH better. If you're going to spend the money on EFI, you really want port injection. Yes it does cost a little more because you need a special intake manifold and 8 injectors....but then you have all the benefits of EFI not just half of them.
