Wholly crap dude you can drive!!!!!! I have no dought with a good tune the bottom will hold that much psi. You are the first person I can think of that boosted thier 420a and installed ems at or around the same time on a stock block. Most people boost the stock motor with a sfmu or fmu. Then blow it up. Then build it. Then if they want more(most do) they go ems. Props dude. Now paint your bumper. lol
