Boost reading on original EDGE juice attitude quit reading
 

I have the original EDGE juice attitude chip I bought the truck with it installed by a local boy I have checked all the connections they seem to be correct. All the reading were working correctly until the other day i got on the pedal pushed it to the floor trying out the power and all of a sudden my boost reading went to 0 but i know i am still getting boost. I have been told it could be the display its self or maybe the MAP sensor. Thats the only place I can find that it could receive a boost reading because it doesn't have a line to the intake or turbo any IDEAS?
I am gonna pull the MAP sensor and try cleaning it tomo THANKS
