I have the same exact car you have to unplug the maf first I believe but make sure you unplug the battery first just to be safe and oh yeah you can run maps 1-3 for what you have installed I myself have the jb4 and down ***** get ready to smell exhaust tho it’s kinda strong running without cats the rest you’ll have to hit up support mines runs just fine
