I see a few cars that have old software but not many, and most power loss problems are not due to old software, but failing sensors or other mechanical issues.
I have the tools to load in the latest BMW software in all cars made up until around 2005, and will be able to do that if someone wants performance software and has an old version.
Yeah that is the moral honest right thing to do imo. advise the customer to fix outstanding drivability issues then and only then upgrade for performance. You know it.
Mark Im not understanding the bolded part. COuld you please expound on it a little bit.
