Interesting your taking the EFI plunge. Curious to see how you have installed O2 sensor. I installed multi-port fast EFI on my comp two years ago. The only issue I have at this point is a slight hunting problem during cold no-load idol. I'm sure the problem comes from a lack of heat at the O2 sensor. When the engine is up to temperature everything runs perfect. Starts with a touch of the key every time, better fuel economy, gain 3 to 400 RPMs on the tack and a couple miles an hour.. Not really a cost-effective add-on but it was something I really wanted to do. I'd be curious to see pictures.
