Default 06 dmax modified cp3 now has p0088 code

Ya so i just installed a industrial injection modified cp3 and fass fuel systemin my 06 dmax , got it all back together and started it up and it throws a p0088 high fuel rail pressure. Check fps. I didnt touch the fuel sensor when i did th cp3.
So is that the problem or is something else causing the problem?
