Hi bros,

Would like some insight of those who understands n54 best. I understand from some mechanics and tuners, if a change in chargepipe together with tial/HKS ssqv, the ECU will die because n54 ecu cannot accept BOV(unplanned air escape)?

Will it damage the ecu and at the same time, loses power from the engine?

Your advice will be much appreciated.
