  1. Challenger Performance Mods - Engine - 5.7L HEMI
    I currently have a D1 procharged Rt challenger...I'm really regretting buying the D1 over the P1 because of a graph that I have seen a few times from pro charger...I have no plans of building my motor or running more than 8 psi. Did I make the wrong decision...it seems like the P1 makes more...
