Why Our System?

 . . . Here's why!

Don't settle for empty promises, GET REAL RESULTS! The other companies make it sound as if it's a benefit to have the ability to "tune" their systems. It's NOT a benefit... IT'S A HASSLE! The reality is, programmable speed density EFI systems are not much more efficient than a 4 bbl carburetor. You're punching keys on a computer, rather than turning screws and changing jets and springs in a carburetor. The end result is an expensive system, that cost almost as much money to get tuned properly as the initial cost of the system. And where is the advantage? They require constant laptop fiddling to keep running properly. You could have gotten that with a carburetor! They are a little more efficient than a carburetor, but not enough to justify the cost. The only thing worse than a programmable speed density system, (besides a carburetor), is a NON-programmable speed density system. Non-programmable speed density systems only work on bone stock or specific applications. Non-programmable (or non user-programmable) systems are factory calibrated to a specific engine, with a specific combination of parts. They have no provision to account for variances such as engine modifications (even minor ones!), vehicle specifics, or atmospheric conditions. The result is, they just do not work very well.

The latest thing being offered by the competition is the "self tuning" speed density EFI system. They claim that their system will tune itself while driving. This is very misleading. These systems DO need to be programmed by the installer, so don't be fooled by their careful use of words. They are far from "self tuning". These systems require you to tell the computer what air/fuel ratio you want under any certain set of circumstances. Keep in mind that the real benefit of a good EFI system is all the knowledge that you buy with it. Our computer comes with all the programing done for you. With our system, you get the benefit of thousands of man hours spent by the OEM fine tuning the processor. It is simply not practical for you, or a dyno shop, to even attempt to duplicate the expertise you get pre-programmed into our processor. Even if you spent months attempting to perfect your tune with one of the "self tuning" systems, it still would not nearly compare to what we give you with our system. Quite honestly, if you're thinking about buying one of the other EFI systems, just save your money and buy a carburetor. Their "self tuning" systems do not offer enough benefit to justify the cost.

In addition, many of the competitors EFI systems are "throttle body" systems. While these may offer some ease of installation, the benefits over a carburetor are minimal. Throttle body systems are not nearly as efficient as our Sequential Port Fuel Injection system. For more information on throttle body vs. port CFI, please see our Q&A page.

Our MASS AIR system does it all for you, and provides REAL PERFORMANCE BENEFITS over a carburetor or speed density system. It is by far the most user-friendly and most effective aftermarket fuel injection system on the market. Get improved power and torque as well as improved fuel economy, performance and reliability. Unlike programmable speed density systems, you will never need to tune this system. No laptop, no hand-held programmer, no tuning or tweeking, no dyno! This saves you the hassle and expense of tuning and trips to the dyno. When it comes time to make further engine mods, chances are you will not need to change a thing on our system. If you plan to make LARGE gains in horsepower, and you need to change your injector size, just return the computer, and we will recalibrate it for you, rather than retuning, reprogramming, and more trips to the dyno. Our system is even easier to use than a carburetor. You need to tune a carburetor. With our system, you just install it, and you're done!
