Default Possible map failure

Hello all Iím new here to the forum!! I have a 2000 24 valve with edge ez fass ddrp aem cold air intake and 4 inch exhaust. I believe maybe my map is going bad? So when I removed my old tuner and put the ez on it throws a po237 code which is map sensor voltage too low. I have had this happen a couple times and it also seems like I have a slight lack in power but Iím not sure. Can someone chime in if they could help out a little!? Thanks
