Technically
Actually you are MPFI, but it is similar to TPI. Pretty much the same, just diff name. TBI is more like "low-tech" fuel injection. In TBI units, fuel is injected like how fuel is delivered through a carburetor. In TPI/MPFI, fuel is injected right above the intake valve.

what he means is that tbi is the bastard child of when got knocked up by a fuel injector. "Better" than carb, not as good as real FI.
