I'm buying a wideband today and need to know if anyone can tell me what will be the issues on my car if I remove the rear o2 sensor instead of putting a new bung in place? I already don't have a cat so I was just wondering what the ill effects would be.
Also do I have to remove the wideband o2 when not tuning or does it just stay mounted.?
And yes I've searched read lots of info just couldn't find these answers.
I was thinking of going with an AEM.. Any other recommendations? I see an AEM failsafe is that worth the extra cash?
