Works!

This Holley EFI got my 1989 Ford Mustang LX with a 347, big cam, automatic going and driving. The factory 89 computer would not run this combo even with a chip I had custom burned. Very good directions, was easy to run through the set up screens. I installed this myself in 4 evenings.

Holly grail

Self install on 90 mustang gt. Typical foxbody with many issues, the Terminator X turned this paperweight in a daily driver. And I have real time information on everything and more.

Holley won't honor their warranty.

Holley doesn't warranty the parts they sell. Their support is useless. The O2 sensor that comes with this kit failed within 2 weeks of installing. Holley won't honor their warranty. Love the Terminator X.
