    Default ECM Boost Limit?

    Hey everyone, sorry if this has already been convered somewhere, but I'm trying to upgrade my MAP sensor to read true boost pressure above 36 psi (22 psi actual boost). I got a universal 100 psi pressure sensor, wired it, and scaled table b0202 to match. It seems to work fine, but my ECM is still maxing out at 36 psi, even thought the sensor voltage keeps climbing well beyond that. Am I missing something in the tune that can be changed, or would it need to be custom mapped? I know Duramaxtuner has a 10 BAR MAP sensor, so they must have figured out a way.
