G20 / F40 Exhaust Overrun / Upshift sounds on stock software? - ccd740 - 01-14-2026
Hi all,
I see this service being offered by many remote coders. Can anyone share exactly how it's done? I'm interested as have an OPF-back exhaust system on my F40, however would want to know exactly whats changed so I know the potential impact to the OPF / cats, but then once I know that I may aswell just VO code or modify my own FA with ėšÝ§...
