I recently had my injectors cleaned by Ford while they were doing warrenty work (Moon roof) and OMG!. I went crusing that night and in crusing manner raced a Mustang (V6) and kicked his ass

I couldnt believe it, made the ATX downshift around 30 and went to 70, the damn thing threw me back in the seat. Its never done that before. I would suggest that you get those injectors cleaned. After all, more fuel = more power.
