Barometric sensor?
 

Simple question, can a barometric sensor be wired LTX8. I live about 3200 ft and my car was tuned around 900 ft, I need to control the need to adjust fuel map just to drive to work 1900 ft. This is a Cali car that's about to get a updated tune, I just need to know just in case I have to get a new ECU...
Thank in advance
