Hi Jeremy,New to the group and just wanted to get some opinions. I have a 2018 RS that I would like to get more power out of. It currently has a full mountune intake, recirculation valve, cold intercooler piping, colder plugs, catback, and tuned on 100 octane by randy from mountune. My latest dyno my car made 356 whp and 396 wtq on a dyno dynamics dyno. Thanks!
