Are you sure it threw the codes because of the broken MAP sensor replacement?
Mine threw code when I drove in the rain, reset it with FORSCAN, then a couple of months later it threw a code when the weather dropped significantly, FORSCAN reset again and all is well now.
Check your T-Fitting because I believe that is the major weakness with the system. Make sure there are no obstruction in it from the 3D printing. I also used worm gear hose clamps, purchased from amazon to tighten up the two ends.
