How do I tune it?
A specific custom tune is installed in the ECU from Motorvation based on the customer's needs, but tuning software is also provided. The software has been designed with simplicity in mind, while still allowing control over all the key functions needed to tune the engine. Street guys and racers who hit a snag can always call the experts at Motorvation for assistance.

How Much?
Kits begin at $2,790 for the basic street system.

Pantera EFI
What packages do they offer?
Most popular engine families are covered by the EFI/DIS conversion packages, including multiple versions for GM LS-series engines, Ford Mod motors, and new Hemis. Pantera's controller can be configured to operate just about any V-8 through their custom kit program.

Pantera's philosophy is that the easiest kit is the one that is most complete. They strive to make everything (from off-the-shelf LS packages to custom solutions) as turnkey as possible.

Best for racers?
The professional racer upgrade includes a custom-designed wiring harness with better materials, motorsports-grade sensors, and custom injector sizing.

What do you get?
Kits include software, the harness, injectors, sensors, intake system, air filters, pumps, and relays. The systems ship with instructions and all receive 24-7 tech support by phone with no "on hold" time.

What options are available?
Polished or anodized finishes on the injection stacks and manifold

How do I tune it?
Kits are pre-calibrated with proven programs, but simple-to-use software is included for those who'd like to create their own tunes.

Professional Products
What packages do They offer?
Professional Products has two different types of fuel-injection systems, the Powerjection II, which is a port-style system that incorporates an intake manifold specifically designed for port injection, and the Powerjection III, which uses a throttle body designed to have the outward appearance of a carb but the function of EFI.

Easiest Kit?
The Powerjection III is a near bolt-on replacement for a carb. Since the EMS (computer) and MAP sensor are mounted directly on the throttle body, a huge amount of installation time and complexity is eliminated. The clamp-on bung for the wideband oxygen sensor also eliminates the hassle of welding a bung on the exhaust pipe.

Best for racers?
While the Powerjection III throttle-body system is being successfully used in racing, its four injectors can only accommodate about 700 to 750 hp. For higher power levels Professional Products recommends the Powerjection II port-style system, which can handle over 1,000 hp.

What do you get?
Both kits include everything needed except the fuel lines, although two hose kits are available. One has enough stainless braided hose and -AN hose ends and fittings to plumb both an inlet and return line from the engine to the tank. The other kit has just enough hose and fittings for an inlet line. The kits are offered separately because some installs don't require a return line when equipped with the FuelOnDemand kit, which eliminates the need for a return line.

What options are available?
The aforementioned fuel line kits as well as larger-bore throttle bodies, bigger injectors, and fuel pumps are available. Custom-built kits for special applications, such as dual four-barrel setups for blowers, are available through the Retrotek division.
