Welcome To The Next Level Of EFI Performance!
Almost since they were first introduced, computer-controlled, multi-port fuel injected (EFI) engines have set a new standard for reliability and performance. But when you are looking to push your EFI engine’s performance to the next level for an extreme street or all-out race application, factory computers -often called ECUs, display a crippling lack of flexibility.

Horsepower-Friendly, Right Out Of The Box!
Aggressive camshaft profiles, high compression, and most other horsepower-increasing modifications seldom run well with even the most radically tuned factory ECU. And if the project at hand is swapping a late model EFI engine into an older vehicle, prospective new “fuelie” guys have to gain a whole lot of electrical knowledge in a hurry, or dig that tired carbureted setup out of the pile of obsolete parts in the back of the garage. That’s where FAST™ steps in to save the day with XFI™ -the easiest to install and tune aftermarket EFI system in the industry!

Quick And Precise Tuning –Only From XFI™
The XFI™ system allows you to fine-tune like never before using C-Com™, its easy-to-navigate software. C-Com™ is completely configurable and allows you to tune your engine for blazing performance without having to work around lame preset factory parameters.

One of the outstanding features that sets the XFI™ EFI system apart from the competition is its revolutionary Qwik Tune™ technology. Qwik Tune™ lets you preprogram up to four different performance tunes –any one of which can be activated by a mere flick of an in-car switch. So you can drive to the drag strip on your “street” tune, flip your Qwik Tune™ switch, and blow away your competitor with your 2-stage nitrous tune. Speaking of nitrous, the XFI™ EFI system can control up to 4 stages of nitrous with its optional power adder harness. And a host of other standard features and available options makes the XFI™ EFI system stand head and shoulders above the crowd.
