I see it's location better now that I've looked on something other than my phone. It's ideally mounted at least 10" from the throttle body in a portion of straight tube. Just hoping you have no tuning/drivability issues as this is definitely a cool idea. It seems like the air moving across the sensor here may not be consistent.

The tuner seems to think it will be ok but will let you know. Getting close...
