If you're running the MAF, the temperature and baro sensor are in the maf.

Thanks for the info. I'm having ECU issues and i suspect it's either in my maf, or lean spool settings. Car suddenly jumps off tune and runs rich under heavy loads.

Check electric connections. It looks like a a false contact.

This is most likely due to your EGR timing adjustments in that load range.
