Holley Sniper OE Style 255 LPH EFI Fuel Pump Modules
Holley Sniper offers OE-style 255 lph EFI fuel pump modules for a wide range of vehicles, including many Chevy, Pontiac, Buick, Oldsmobile, GMC, Ford, Mercury, Jeep, Dodge and Plymouth cars and trucks from the 1950s, '60s, '70s, and '80s. These in-tank modules are high-pressure units that flow 255 liters per hour (LPH) and are capable of supporting electronic fuel injection (EFI) engines producing up to 550 hp. A pre-calibrated fuel level sending unit designed to work with the factory fuel gauge for this application is included. Each module also features a HydraMat filter which has a unique internal reservoir that keeps fuel available at the pick-up and also provides protection from contaminates. Fuel pressure is internally regulated to 58 psi, eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator; no separate return line is required because these modules return excess fuel right inside the tank! The Holley Sniper EFI fuel pump module was designed as a direct replacement for your factory pick-up and sending unit. There's no need to purchase a custom EFI fuel tank. You can even retain the factory fuel hard line—just connect the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps available in the Earls Vapor Guard line.

Holley Terminator X MAX GM 6L80/90 Transmission Kits
Add GM 6L80/90E transmission control to any existing vehicle utilizing a Terminator X Max ECU. A departure from traditional Holley EFI transmission control, the Terminator X Max ECU allows the ability to use 2007+ GM 6L80E and 6L90E transmissions by communicating via CAN with the internal TCM (Transmission Control Module). The supplied Holley EFI OBDII transmission tuning hand-held is used to adjust shift points, tire size and gear ratio. Terminator X V3 software provides the ability to dial in torque management to optimize the desired shifting characteristics when using a 6L80/90E transmission. The software also enables you to control the secondary shift mode within the transmission TCM and allows use of tap Up/Down shifting. Within Terminator X V3 PC Software: --- Virtual Torque Management Tables --- Virtual TPS Tables to dial in shift characteristics regardless of engine --- DBW and Timing torque reduction tables to create smooth shifts Within the Holley EFI OBDII Transmission Tuning Hand-held: --- Ability to read and clear TCM fault codes --- Ability to raise and lower shift points by MPH or RPM --- Support for Tap Up/Tap Down & Transmission's Secondary Shift Mode If you currently have a Terminator X ECU, upgrading to a Terminator X Max ECU can be easily done by plugging your main harness into the Max ECU and re uploading your existing calibration. Holley Terminator X MAX GM 6L80/90 transmission kit features: * Included TCM hand-held tuner with integrated wizard is required for setup in conjunction with the Terminator X 3.5 in. hand-held. Terminator X V3 software unlocks optional tuning parameters. * Plug-and-play with any engine controlled by a Terminator X Max ECU * Supports: Shift Mode - Tap Up / Tap Down, and torque management * Four loose wires: --- Power (Red): Supplies power to the transmission solenoids. This should be connected directly to the battery, or a constant battery source capable of supplying 5 amps --- Ground (Black): Connect to a good chassis/engine ground source --- Brake Switch (Light Blue/White): Wired to the brake light switch. This must be installed to a +12 V source (as most brake light switches are) --- Park/Neutral Safety (Yellow): Circuit for starter solenoid. When the transmission is in Park or Neutral, this yellow wire will be grounded (-). When the transmission is in gear this circuit will be open.
