2001 24v evee I get on it build a ittle boost and let off the truck shuts off and gets airbound. Truck has a upgraded xdp vp44, sumped fuel tank with a fass, over sized lines, 125 injectors,edges juice w/ attitude, blow off valve, aurora 5000 (removing soon). It keeps piping with a p0121 and p0122. I reset the tps and still nothing. Yesterday and today I was getting a dead peddle and I just pulled over cleared the codes and drove. The vp44 is still under warranty but I'm going to test it tonight before I send it back. Any help is much appreciated. Thanks -matty
