From what I’ve heard the tune isnt what messed that car up, but the lack of fuel it was getting… Im not an expert by ANY means but usually when going with a high end fuel system you need to use very thick gauge wiring… Alex’s cars fuel pump was wired with speaker wire he said which obviously isnt thick enough which I would believe it to not get enough fuel? Not sure who did the fuel pump/s install but I would think that’d be the reason his motor was damaged?
