Haven't heard about the injectors yet, but can't say mine are noisy. People complain about 02's and coolant temp sensors with the fitechs also. Remember that some people trying to install these are too stupid to work out a carby, so theres a good chance the o2 is in the wrong spot or their issue was self inflicted. Widebands are also somewhat of a consumable, especially running race gas which I'm sure is the culprit in a lot of cases. Leaded gas, which race gas has a lot of, will stuff it real quick. Fitech supplies a stupid "clamp on" o2 install kit in the box. Basically 2 hose clamps, some rolled sheet metal with a nut welded on it. Using this would also be asking for issues I think. Idea obviously is that you just drill a 20mm or so hole and put this thing over it. The supplier mentioned a couple of cases of stuffed o2s due to bad installs.
