Features
Vehicle Compatibility and Return Conditions.
This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.
Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.
Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.
Images are supplied by the manufacturer and may be generic. While all efforts are made to provide accurate pictures, there may be differences in the actual product, such as colour, quantity, version, or included components. Please carefully review the description and specifications for details on inclusions or any variations. Some items may be sold individually or in sets, and images may occasionally depict additional products or quantities not included in your purchase.

Ultra Ram 650 HP Chevy Small Block EFI System With Master Kit
FiTech's Ultra Ram EFI 650 hp in-tank pump/regulator/Go-Spark fuel injection master kits feature their outstanding Ultra Ram with aggressive looking sheet metal intake manifold along with an in-tank fuel delivery system. Also included in these packages is a Go Fuel Tight Fit regulator with gauge and a Go-Spark CD ignition for high-powered sparks that improve combustion and power output. Designed for the do-it-yourself hot rodder to the professional EFI tuner, these kits are ready to go with everything you need to convert your carbureted engine to top-of-the-line EFI FiTech self-learning technology.
These Ultra Ram EFI systems will support up to 650 hp and come out of the box with the injectors and fuel rails installed. The robust ECU is easy to mount and handles the air/fuel mixture targets and you only need to input a few engine specs into the color touch screen monitor to get the engine to rev up. Ultra Ram is supplied with a sheet metal intake, cast aluminum 92mm throttle body, remote mount ECU, main harness, handheld controller, cable and windshield mount, WBO2 sensor, bung kit, coolant sensor, gasket, mini USB cable, instructions, and warranty info.
For fuel delivery, these FiTech Ultra Ram master kits include either a Go Fuel in-tank 255, 340, or 440 lph pump module. They can be used on tanks with a depth of 6 to 15 in. and feature a billet top assembly designed with the supply and return ports in a parallel position to help route the fuel lines easily and evenly. A vent port is on the other side to ease routing the line near the fill tube. The two fuel ports are threaded to accept -6 AN O-ring boss fittings for a secure, leak-free connection.
The Go Fuel Tight Fit regulator can be adjusted from 30 to 70 psi and will support up to 1,000 hp. It is crafted from billet aluminum, features -6 ORB ports along with a vacuum/boost port, and includes a gauge.
Go-Spark CD ignition produces a series of multiple sparks below 2,500 rpm to improve starting, idle quality, and throttle response. Designed for 4-, 6- and 8-cylinder engines equipped with a distributor, it accepts the trigger signal from an HEI, amplifier, points, or 2-wire non-magnetic pickup distributors. A separate 12 V square wave tach output can be used to trigger the EFI system and/or a tachometer.
