Default DSX auxiliary fuel pump install/ map sensor failure

Just wondering if anyone can help. I recently installed a DSX auxiliary fuel pump in my 2012 ZR1 and now Iím getting a code saying saying Low map sensor signal. So I unplugged the DSX wire harness, unhooked the power to the pump and installed the factory map sensor connector to the factory map sensor, still acting like itís in limp mode. Any help would be greatly appreciated. Did the factory map sensor crap out on me? Also I havenít had a chance to get it tuned, is there something in the fuel setting on my hp tuners that I need to change?

Contact the owner of DSX on Monday morning. He is a master tuner.
