Ian, as an investor in all 3 generic 569 / unlocked ECU combinations, the KH S&S map, the G56 S&S map and the G56 Emerald Map, I’ll be really interested to see what improvements a good technician can make on a custom tune to a specific engine. I’d agree with you that any individual tune is likely to be better than a generic one, and look forward to hearing if you think it’s worth the additional expense. If you’re happy then I hope you’ll share the details so we can benefit from your initiative.
