I'm a believer in tuning with a wide band O2 sensor. I've used the Innovative handheld quite a bit but later installed the kit for in-dash A/F meter. I use the Speedhut gauge since it matches my set of gauges. I have bungs in both collectors, installed at about 60 degree angle. Not noticeable unless you are looking for it. Good feeling when you can see how your fuel mixture is behaving under all conditions, whether carb or EFI.
