Please base dyno run, install, re-dyno…post on bimmerforums. That would be a job well done. I’m sure Albany Speed will work with ya for the marketing aspects. That thread will fly.

Already have an apointment at Synapse tommorow at 11 to dyno car stock… Directly after dyno im gonna drop it off at Autohaus… When done, ill dyno it again.
