Just installed my innovate wideband last week but my AFRs are reading really lean. I have DTLT headers, urd y pipe and a vibrant resonator. Has anyone else with a 2012+ xrunner see this problem? I mean when I'm idling it's reading 17-19's. I know the wideband is tuned because we did that before anything. I'm thinking i have some really bad exhaust leaks somewhere. Any info is appreciated! Thanks!

That's another thing. I know there are bungs already on the headers. But because it's a v6 technically aren't we suppose to have 2 wideband to read both sides? I ended up welding a bung right after the y pipe. I knew the gauge wasn't going to be accurate because it was so far away but I didn't think it was going to be this inaccurate if that's the problem. And yes I did free air calibrate it correctly.

If it's in the y-pipe or after the y-pipe you have multiple spots where you could have exhaust leaks affecting those numbers.

Exhaust leaks. Look for soot around all of the flanges, and double check that all of the hardware on your exhaust is tight.
Also, when you installed the long tubes, did you also install new Y-pipe gaskets? Preferably the URD heavy duty ones.
