heres your basic TBI or Throttle body injection

heres your basic TPI or Tuned port injection

TBI or TPI refer to the type intake or fuel delivery system used there both a type Electronic fuel injection or EFI

TBI is the specific EFI type.

"EFI" just means "electronic fuel injection". As opposed to "mechanical fuel injection".

EFI comes in many forms, one of which is TBI.
