Tuning for air intake errors

[clifftoo]

When moving to more air I am finding we are getting some errors here and there like p222b.

I was thinking it is related to the aircharge conversion.

I've yet to see that code, and I get a lotta codes. Barometric right? I don't even know where that sensor is located but I'd assume it would just be sitting somewhere in the eng bay, not touching the engine? So you're saying the code trips at full throttle or?

To fix the issue,

the sensors located on the Air Filter Box are called Barometric Pressure Sensors most people tend to think they are MAF sensors which is on that case not correct !! As these platforms operates on MAP sensors and getting feeds from Baro sensors to calculate right amount of boost.

I would suggest whenever replacing Air Intakes or Spark Plugs to replace them too as over time they may function but loose the ability to send correct signals to the ECU which cause P222b or loss of boost.
