I’ve thought about the same thing. I think the pickup truck tuners wire a “dsp5” switch into the ecm pins for the barometric pressure sensor and jump through different operating modes that way but to do it proper would require a whole lot more tuning than what they bother to do plus you lose information the ecm needs to calculate proper offsets.
