Hello guys so I'm just curious I have a 2009 cobalt ss tc that I am currently trying to mod and just trying to get all the facts straight. Right now my build consists of k&n intake, Going to be getting a ZZP bigger intercooler, Upper and lower charge pipes, and an offroad downpipe. My question is do you need a wideband when I go to get the car tuned? Therefor do I need to buy a wideband and have an o2 bung? Also do I need an angled one or just the regular o2 bung?

Nope our car has a built in wideband.

Does it matter that mine doesn't have the rpd? So When I get it tuned. (planning on an hpt tune) I wont have to put in a wideband for the tune?

Nope hp tuners logs through the wideband you can see the air fuel through the chart and histograms on my scanner

Many direct injected engines these days come with wideband O2 sensors, so it makes tuning them incredibly easy.
