MultiNav Pro+ sensors module - temp/pressure readings offset at high altitude?

💡 Idea
Hey all, been integrating the MultiNav Pro+ sensors module into a high-altitude balloon tracker and running into something weird with the temperature and barometric pressure readings once I get above around 8,000 feet (simulating altitude in a pressure chamber for now). The temperature readings start drifting noticeably low compared to my reference sensor, and the pressure values seem like they're lagging behind real changes - almost like there's some internal smoothing or averaging I can't turn off. Anyone else seen this at altitude or in low-pressure environments?
