Wideband bung location on downpipe? So I made a dp for my lq4 gt45 chevelle swap, it has 7in after the turbo outlet before it necks down at the firewall and straight to the ground, where do I need to weld the bung to? It's an aem wideband running microsquirt computer tuning

At least 1ft after the turbo and not on the bottom of the downpipe (moisture). Mine is about 4ft after the turbo and 3ft before the end of the exhaust. You want it away from the turbo for heat and not too close to the exit because it can reverberate (think that's the right word) and get some fresh air on it at idle and low rpm messing up your readings.

It depends on the diameter of the down pipe. I've always followed this rule.....
If it's a 2" down pipe 2x10=20" away from turbo,
2.5"x10=25"
3"x10x30" from turbo you get the point.
But that being said I also try to keep it at least 6" away from the end of the tailpipe.
