Per your commentary, you could not raise redline.Guys, when you swap the ecu they will still know.. dont think swapping in and out will get your warranty warranted when you get engine related problems. They will see every rpm increase above 6800 and by default it is void. Our friend here had een problem with the engine/rpm related no need to go into details. Needed a brand new engine and it was not covered by warranty I can tell you that.
Once 3 years warranty is over id say unleash the beast, before that if you dont care about warranty.. but dont think doing all shit to the car and swapping the old ecu will cover your ass.. it wont!
Runtime will show gaps but absence of info isn’t proof of anything. Simply absence of info
