What is everyone's opinion on BMW doctor video on upgrading power and speed through programming using NCSExpert to chnage the power class?
I did the Bimmerlabs 330i tune to increase power. Is this needed? I ordered a 3 stage manifold which is coming soon and cannot wait! BMW doctor says this increases full power of the car and also removes the speed limiter or increases it. BMW wants to keep this a secret according to him to sell high trim cars.
Is the Bimmerlabs 330i tune enough or do we need to do this?
