Hey guys I’m looking to get a piggyback for my stinger. I have jun downpipes and k&n filters. I was looking at the racechip Rs or the jb4. I would probably not use the fuel wires as I don’t want the dealer to see it. Any info would be great! FYI I put 91 in my car but we do have 94 down here as well and I’m going to get my stock plugs put down to around 25.
