Got another question regarding this. During the breakin should leave my front o2s unplug? Its untuned at the moment but im not running any cats, have bigger cam and I believe there may be some exhaust leaks. [/b]
No, keep your front O2s installed and hooked up. It&#39;ll never go closed loop without them and the fuel mixture will be much more accurate with them.
