I have the dinan ecu which raises it by another 200rpm, the redline in the cluster is at 8250, above the half point which is 8500. I guess bmw was too cheap to make an actual 8400rpm gauge, they took this right off an M5 and just recalibrated it. 8400 = 8250 on the physical rev counter... just wondering about my dinan
