A quick search online and in general I see shops which offer remote tuning services by either emailing new maps when provided log data or they’ll even tune it while you’re on a dyno local to you. So you could rent dyno time and maybe get g56 to tune it remotely? I think if you get g56 to play ball, or some other tuner with emerald knowledge, and find a local dyno (or just road tune) you can get this done.
