Hey guys need some help. A friend of mine bought a 6.7 powerstroke with h&s mini maxx and dpf delete. We just installed a egr delete kit and now we are having manifold absolute pressure code P0107 and the boost gauge in the cluster is pegged and the gauge in the mini maxx isn't working. I believe it's a newer version mini maxx, Any help would be greatly appreciated
