"Corona, CA - RetroTek Speed is set to rock the automotive aftermarket with a stunning leap into the future of fuel system design. The affordable, high-performance, easy-to-install BossEFIâ„¢ complete fuel injection systems will bolt on to any engine with a four-barrel carburetor.
Thanks to RetroTek's revolutionary new self-learning Smart Tune Technologyâ„¢ (STT) ECU, you don't even have to program the system. Simply plug in the harness, hook up power and ground wires, and drive. Within minutes the vehicle will be running smoother and more efficiently than it ever could with a carburetor. Most importantly, the BossEFIâ„¢ system fits on any four-barrel intake manifold, supports up to 1,200-horsepower, and is compatible with blow-through and draw-through supercharger and turbo applications. Thanks to external dimensions identical to a carburetor, it will even fit under your stock air cleaner, shaker hood scoop, or cowl induction. For the first time in history, enthusiasts can add a complete, high-performance, digital fuel injection system to ANY vehicle without hassling with complicated installations or advanced computer programs.
Here's how it works. The patent-pending Boss750â„¢ and Boss1000â„¢ injector bodies are dimensionally nearly identical to a standard carburetor yet represent a giant leap forward in fuel system technology. These are NOT like the old-fashioned TBI systems that were bulky and low-performance. The RetroTek BossEFIâ„¢ Injector Body uses port-style high-pressure fuel injectors, which are hidden in the "float bowls." One high-pressure injector sprays into each of the four contoured max-flow venturis. Both 750 and 1000 cfm bodies are available to suit a variety of applications. The units are compatible with standard carburetor linkages and components, including nitrous and superchargers.
The second component is the "Flow Control" pressure regulator. Rather than forcing a consumer to rip out their old fuel system and install complicated fuel return lines like old-fashioned aftermarket systems, BossEFIâ„¢ only requires one fuel line and a standard EFI pump. The Flow Control system modulates the pulsewidth of the fuel pump, meaning it can regulate the amount of pressure the pump makes to match fuel injector demand. This allows the Flow Control unit to modulate fuel pressure up to 60 times per second, so air/fuel ratios are always precise and there is never excess pressure in the line.
The "brain" behind the operation is the third and final component, the RetroTek Smart Tune Technologyâ„¢ (STT) engine management system. About the size of a paperback book, the STT is a totally new concept in fuel injection control. Simply take it out of the box, plug it into any computer (desktop or laptop) with a USB or serial cable, and choose one of the pre-loaded programs that best describes your engine. Simply highlight, click, and you're done. Then install the box in your car.
The Boss750â„¢ Injector Body is pre-wired with a wiring harness, which snaps into the side of the control box. Add positive and ground leads from the battery, an ignition lead, a lead from the coolant temp sensor in the intake, and snap in a wide-band O2 lead, and you're ready to go. Everything else is pre-wired, and the injector body is an all-inclusive EFI system. No fuel rails to plumb, no extra wires to run or sensors to install, and no headaches. Hit the ignition and the basic tune will get the motor started. At that point the STT System will start checking air/fuel ratios 60 times per second, until it creates it's own fuel curve. Drive around the block and the system will continue to learn, until engine operations reach peak efficiency. As your driving style changes, the STT will continue to adapt.
For those who want to alter or modify air/fuel ratios, all they have to do is plug a computer into the STT, and type in the desired air/fuel number. The STT will do the rest. The engine tells the computer what it NEEDS, not the other way around.
There's no longer a reason to abandon tried-and-true intake setups to convert to EFI. Use your proven manifold while adding all the benefits of turn-key fuel injection. The injector body, STT Computer, and Flow Control regulator are all available as separate components or in complete kit form. The BossEFIâ„¢ system is compatible with a variety of ignition systems, including MSD, HEI, Pertronix, points, Ford Electronic, and even coil pack/crank trigger systems. It is also fully compatible with standard throttle shafts, cables, and even transmission kickdown cables. Muscle car, hot rod, off-road, and marine performance enthusiasts finally have a viable, inexpensive, easy-to-install EFI solution that offers all the performance and reliability of a finely tuned port-injection system, with the simplicity of a carburetor.
The RetroTek Boss750â„¢ and Boss1000â„¢ have undergone extensive dyno testing, and will meet or exceed carburetor and standard EFI system power numbers on even the most radical race motors. The testing and prototype development phase is complete, and systems with will be on the shelves Spring 2007.

Pricing according to RetroTek Speed will be in the $2000 target range for the entire kit which will include a fuel pump good to 500hp.
Here is a e-mail from RetroTek Speed,
Thank you for your interest in the all-new RetroTek BossEFI system. The
story in Hot Rod magazine came out a little early and our site was not ready
to go up so we will be adding info daily.
PRICING
To answer some basic questions, the system is set to target the $2000.00
price range for the 930cfm body and comes as a complete package. The
Throttle body bolts in place of a Holley or similar 4 barrel and has the
same overall dimensions, so the air cleaner will remain in the same
location.
SELF-TUNING COMPUTER
The computer is the first self-tuning system available and is a speed
density ,closed loop system . We use a PLX wide band (included) and the
system delivers hands free tuning at all loads and RPM²s. The key to our
system is its VE SYNC which reads the air fuel of your engine and re-writes
the base fuel table to deliver the exact Target Air Fuel ratio desired for
your engine. This can be done while viewing the info on a laptop, or without
one. The system re-programs itself so the oxygen sensor does not have to
work to correct an inaccurate calibration each time you run your engine.
Once this is done you can leaved the O2 in place to compensate for various
fuel and elevation differences. A video demonstrating a system being tuned
will be posted on the site shortly so keep checking it out.
ADDITIONAL COMPONENTS
The kit comes with a high pressure fuel pump that mounts on the chassis at
or below the fuel tank . For over 500HP and larger applications, an
ultra-high performance pump is required for an additional charge. Also there
is no need for a return fuel line although one may be used along with an EFI
bypass regulator. The return-less system is included in the kit but the
bypass style system is not included and can be purchased separately.
ECU & WIRING DETAILS
The computers dimensions are 6-inches long, 4.5-inches wide, and 1.65-inches
high; and it can be mounted either under the dash or in another dry
location. All wiring features weather pack connectors and are completely
terminated although you are required to install an o2 sensor bung in the
exhaust pipe. This can be done in one side only by any muffler shop and the
bung is included.
SYSTEMS AVAILABLE
There BossEFI comes in 2 sizes, 930 & 1200 cfm ratings. The 930 will handle
up to 650hp and the 1200 is good for 900+hp with the correct size injectors.
There is a simple formula to size the injectors. We use 4 so the math is:
HP divided by 2 /4 = injector size.
The computer is capable of very small pulse widths so it is better to be a
little large in this area. An example of this is 500hp/2/4 = 62.5lbs. In this
case we would use 63 lb injectors.For Dual Quad systems we would have 8 injectors so HP/2/8= injector size. 500hp/2=250/8=31.25. We would supply 8 32lb injectors in the kit. You can use this simple math to work up any HP combo you have. This is a Quick tip only,call us if you are un sure. All necessary sensors are included so
this is a true bolt on system!!
RELEASE DATE & FURTHER INFO
We will be sending out periodic emails with more details about the BossEFI
system up to the Spring 2007 release date. Please stay tuned, as THE MOST
EXCITING NEW PERFORMANCE PRODUCT IN 20 YEARS is about to REVOLUTIONIZE your
vehicle.
you might want to keep in mind its basically a throttle body injection system and while it in theory beats a carb, its never going to beat a MPFI set-up for f/a ratio control to each cylinder due to the design limitations
