This is a 91 pump gas tune for e36 obd1 red tag ecu. Originally it was tuned by Jordan at RK but from what i was told by the previous owner, since he was sponsored by TRM he had them go back through it and tweak some things that didn't make him happy.
I was going to use this tune for my build but I'm going E85 and so ill be getting a fresh tune for my setup.
PM me if you are interested.
