Direct Fuel Injection - Adding Fuel To The Fire - Tech Talk

I then asked Trey if he could foresee a point where DFI will represent a meaningful advantage to tuners, so much so that people will be looking for ways to convert from port injection to direct injection? "DFI offers a precision of control significantly better than non-DFI setups. So, in theory, yes, you should be able to make more power and, most importantly, consistent power. So I think DFI will eventually become a sought-after advantage. However, I do not foresee people converting their existing non-DFI engine over to DFI in the near term. The systems are (at least currently) too complex and ultimately need to be done with the mindset of creating an entire system. Engines are mechanically designed to have DFI or not. Unless a complete package can be developed with a low enough cost of entry, I think we'll only see DFI used on applications it came with from the factory."

With more and more gasoline-powered vehicles being equipped with DFI systems from the factory, including machines from manufacturers like Mitsubishi, Subaru, Mazda, Toyota, Isuzu, BMW, VW, Audi and GM, it's safe to say the aftermarket will find ways to take full advantage of the benefits associated with this technology. With companies like Cobb Tuning taking on the challenge already, you can rest assured that your DFI car will have just as much (if not more) tuner potential as its MPFI counterparts.
