Terminator Throttle Body Injection (TBI) EFI Systems were Holley's original 4150-carburetor replacement EFI Systems. Predating the Sniper EFI System, these include one of Holley's high-end HP or Dominator ECU's mated with a 4-barrel throttle body with four 80 pound-per-hour injectors. Air flow is an impressive 950 CFM, making this an appropriate choice for naturally aspirated engines up to about 600 HP or boosted engines to about 480 HP (gasoline.) Optionally, an injector upgrade is available that will allow naturally aspirated horsepower levels up to the limit for 950 CFM of airflow (roughly between 700 and 800 HP) and over 1000 HP boosted.
- Easy to install
- No computer experience required
- Handheld tuner included
- Simple multiple choice set-up wizard
- Self-tunes while you drive
- Optional Laptop Tuning capability (no cost--free download.)
- Available in Polished (550-405 & 550-407) or Hard Core Gray (550-406, & 550-408) Throttle Body
Fits all standard square flange intake manifolds. Connections for Ford, GM TH350 and 700R4, and other transmission linkages.
While similar in scope to the Sniper EFI systems, the Terminator TBI systems have some features that set them apart from Sniper. To name a few:
- Remote-Mounted ECU typically much less sensitive to radio frequency interference (RFI)
- Capability to drive Holley EFI Fuel and Oil Pressure gauges*
- Knock Sensor Capability*
- Water Methanol Injection Capability*
- Internal Data Logging
- Fully Programmable I/O
- Customizable Sensors
- Alpha-N Load Sensing
- More Advanced Boost Control
- 8 stages of Nitrous
- Traction Control*
- Staging Assist
- Transmission Control
- Timing Control Compatibility with GM HEI or Ford TFI Ignitions*
*Requires additional hardware not included in the basic Terminator TBI system.

Available With Transmission Control
Owners of vehicles with the GM 4L60E, 4L65E, or 4L80E transmissions are really going to like this--the Terminator Univeral Throttle Body EFI System is available with transmission control for these popular transmissions. Easy setup on the handheld display using the same setup wizard that creates the configuration for EFI control. Once configured you can use the handheld to fine-tune the upshift and downshift points, WOT upshift, torque converter clutch parameters, and more. You can even tune the line pressure vs. TPS or MAP for each gear!
Fuel System Upgrade Options
You probably recognize that you need to upgrade your fuel system if you're upgrading from a carburetor or the old GM throttle-body injection to this Terminator TBI kit. Fortunately, you have a lot of great options! We have fuel pump modules to fit a broad assortment of gas tanks, complete EFI fuel tank systems fit many popular muscle cars and trucks, and you can even choose to order your Terminator 4BBL TBI system as a Master Kit with all of the components shown in this image. If you have any questions at all, just contact us and we can help design a fuel system that is perfect for your application!
