Look at the power numbers from the other ports compared to ours, and also look at the individual things the ports for other cars can do compared to ours. The one they have for the 135i makes the most power with the most perks. Also, prob more difficult of a flash due to our more difficult to mess with ECU
Not every car's ECU is the same obviously, more computing, more work, more labor all mean more money
