Dragula & Mike,

So if I decide to buy the Holley FI, it looks like I would buy the Holley Dominator ECU, the Fuel Injector wiring harness, Fuel injector rail kit that includes the injectors...

Would I need to run two O2 sensors, one on each side of the headers?

The harness kit for the o2 sensors, two 1000 cfm throttle bodies...but Holley sells 4 styles?

Anything else I am missing, since I do not see a complete kit for sale for direct port injection...and will the Dominator ECU self learn?

Sorry for all the questions, but if the Holley system is better than the FiTech, I would like to know before I open the box.

Thank you, Mark
