I just changed my 24lb injectors to 60lb over the winter in my Stock Eliminator LT1. I'm running 45 lbs fuel pressure. From all my research it seems it's best to run the fuel pressure at the injector rated pressure which is usually 43.5 lbs. Some people compensate for too small of injector by increasing pressure. Are you sure your O2 isn't being contaminated with an exhaust leak. Where is your O2 located?
