Since you guys are talking about tuning and I'm going down that path soon, I have a question that might relate to it. What's the purpose of the bung on the header after the collector? I've learned you need it if you want to have a wideband gauge in your car, but is that it? Is it necessary to have this header bung to do tunings? Also is it easy to seal or cover it up? I've got a header on order that has it that's why I'm asking.
thanks
