Oh. Well, I ran a 4th injector on my last turbo insight and I hated it. I always feared cylinder #1 was getting most of the fuel and #3 was lean, but there was no way to prove it. Also, the computer for controlling the injector is 300$, while the AEM piggyback is 400. Definitely worth the extra cash IMO.
