Easiest kit?
Inglése says their FAST EZ EFI system is the most user-friendly stack system ever introduced. Like FAST's own kit, if you can read and answer a few questions, with the push of a button you can have an individual-runner EFI system up and running in no time.

Best for racers?
For hard-core racers, the XFI kit is the no-compromise answer, and features built-in boost control, multi-injector control, sequential rev limiting, and options like internal data-logging and traction control from XFI. And it still looks like Webers!

What do you get?
Complete kits include everything from the ECU, manifold, stacks, injectors, harnesses, and even the fuel kit. Inglése also offers all of their parts individually so that customers can custom tailor systems to their specific needs.

What options are available?
Inglése systems can get flashier with show polishing service, chrome plating, custom painting (with paint code supplied), anodizing, powdercoating, and even things like custom fuel line material options. Inglése says they can usually help come up with something unique that is aesthetically pleasing and complementary to the vehicle.

How do I tune it?
On the EZ EFI systems, it's self-learning, so there's really no tuning necessary. On the more exotic stuff with XFI, the software has over 25 pre-built tuning files that one can use as a base tuning file in many applications. From there, Inglése's dealer network really comes into play, offering on-site dyno tuning or remote over-the-web tuning.

How much?
EFI systems start as little as $2,999.95

Mass-Flo
What packages do they offer?
The two main kits are very straightforward: single or dual throttle body. The single or dual decision is made based on the customer's preference or flywheel horsepower. The engine can be supercharged, turbocharged, have nitrous, you name it, and Mass-Flo says they can likely build it. In addition to full systems, Mass-Flo also sells components separately for those who already have some type of EFI system currently installed.

Easiest kit?
Because of the never-tune-it design of the Mass-Flo system, they're all equally easy. If you can follow the installation instructions, you can have EFI.

Best for racers?
All of the systems can support high horsepower, but guys making big numbers may need a dual system.

What do you get?
The Mass-Flo system includes your choice of intake manifolds, custom 1,000-cfm four-barrel throttle body complete with idle control motor and throttle position sensor, high flow 9/16-inch diameter bore fuel rails and mounts, custom compact high-flow mass air meter, complete wiring harness, mass air sequential electronic fuel-injection computer, eight fuel injectors sized to your application, all sensors, billet aluminum distributor with ignition module, rotor and cap, throttle cable bracket, assorted hardware and fittings, and detailed instructions for a turnkey installation.

What options are available?
The main decision is whether you want the engine to have a classic look or a modern EFI look. The classic look will use a standard air cleaner on top with the air meter concealed inside, while the modern look uses a Pro-M Racing mass air meter and is set up more like a late-model muscle.

How do I tune it?
By design, there is no need to tune the Mass-Flo EFI system; it's all self learning.

How much?
The average Mass-Flo system retails for around $3,000.

MoTeC
What packages do they offer?
Current packages are the STMCHEVV8 kit for big- or small-block Chevy engines, the LS kit for LS Series engines, and the easy-to-install Three-Wire EFI kit.

Easiest kit?
The Three-Wire EFI kit is the easiest kit offered, and it's backed by FASTMotorsports' exclusive guaranteed-to- start-and-run Basemap that is included. It doesn't control the ignition initially but you can easily make a few more connections and have timing control too if desired.
