Holley HP EFI for TFI Ford (NTK Wideband)
Holley Part #: 550-606N
Matt's Notes: We run this as the base kit to install Holley EFI on a TFI Ford. We run this with 5.0 Pushrod Mustangs (Fox and SN95) as well as 351W Gen 1 Lightnings. When using this with the early Lightnings you will need to change to a "push start" TFI module. It is otherwise plug and play with the Mustangs and requires minor wiring from the distributor to updated TFI on the Lightning.
We can assist you in installing this kit on a Mustang or Lightning.
This particular kit comes with the NTK wideband. We also offer it with the Bosch wideband for a reduced price. Please see our other offerings.
This kit ships with a one bar MAP sensor. If you intend to use this kit with boost, you will want to purchase a three bar MAP sensor to use with it in most instances (up to 29.7psi of boost). The higher capacity MAP sensors are available in the "sensors" section on this site.
This base kit does not include the harness for inputs/outputs. Please add that as an option with the drop-down if you intend to use inputs/outputs.
Looking for a alternative for your stock or built late model factory FORD EFI engine? How about a replacement ECU for your older Holley C950? Holley has you covered. HP EFI ECU and harness kits are designed to be used with popular factory EFI engines as an alternative to the factory ECU and harness or as a replacement for your C950 ECU. The HP allows you to accurately control the fuel and ignition of your engine along with additional controls for nitrous, boost or water meth.
