For us, the most impressive thing about the massive movement that racers and hot rodders are making to EFI (in its various forms) is how companies like FAST have spent the time and resources to make their systems so user friendly and compatible to the needs of their customers. From drag racers who are looking to run repeatable numbers on every lap down the track to street rodders who are looking to have a car that starts and delivers great on-road performance, companies are making offerings to fit everyone’s needs.

One of the most popular offerings on the market is the Fast XFI Sportsman kit that can be had with a throttle body. Capable of supporting 1,200hp, boost, nitrous, and virtually whatever else you can throw at it, this is a system that can work in a return or a non-return configuration and has all the functions for tuning that you could want. It is designed to deliver the data and tuning you want without a lot of functions that sportsman racers or weekend warriors may not be looking for. It is truly designed for those who are looking to make the EFI change and have some say in how the system works.

The FAST C-Com software which is included with the unit so you can literally plug and play. It should be noted that the Fast XFI sportsman system can also be used to fire a multi-point fuel injection system as well for the ultimate in fuel control.

We dig this throttle body system, especially for drag race applications where you need to be able to tune the car for the conditions. Neat stuff from FAST, check it out here!
