Strange one guys. Had my s3 mapped at my door, standard ecu tune around 360bhp. I then fitted an r600 performance air intake and a res delete. Car ran fine for a couple of months but I’ve had 2 gearbox malfunctions over the last couple of days when I’m driving hard. Car goes to redline stays there doesn’t !Removed! and the into limp mode on the gearbox. It’s under warrenty 🫣 so I’ve take the air filter and res delete out and taken her a drive. No she’s running fine. Shifts are perfect. I know it sounds crazy but in any way could them mods after the map cause a gearbox issue or has anyone had a similar problem. Thanks. James
