Holley EFI 550-851

Right from the moment I opened the box THIS unit was a pleasure. If was so easy to install, set up and the vehicle runs beautifully with it. The weather here is cold and damp and the car doesn't miss a beat. There is a noticeable gain in power, and it seems the fuel economy has increased - so that's another bonus. I would recommend downloading the installations instructions and reading them fully. I received the unti and after reading the instructions had to order some complimentary parts to meet the recommended fitting requirements. I needed a fuel pressure gauge, new ignition wires and some additional cable to extend the loom. I installed the extra parts and connected the unit exactly as the instructions stated. Turned the key and the vehicle fired up, ran super smooth and I haven't stopped smiling since. Well worth the money and really well priced for the level of tech you get. My vehicle is a 1979 Holden ute with a 202 cu in straight six, auto trans.

I originally ordered the competitions EFI - that was not a good experience. I ordered this unit after becoming completely frustrated with the other one.
