I have some questions (not sure if this has been asked)
So my understanding is that this tune works of a 330i mapping. However, lets say I install a 3SIM. In the ECU, there is a programable setting for powerclass (a 328i is on medium power class). If I were to just switch to high power class, would that also enable the power gains?
Also, does this tune only work of a 330i powermap? A 328i with the updated n52 engine goes up to 260hp (seen on the x3 and such) but the 330i only goes to 255hp. Both engines are slightly different, and wouldnt flashing the powermap of a lower ouput engine ruin the new n52 engine?
Sorry for the noob questions, just curious here
