Active Autowerke has released their X5M and X6M twin turbo V8 software. This is a flash tune available for either 91 or 93 octane. Active has provided a dyno showing nice gains through the curve. Do not just focus on the peak numbers as they do not tell the whole story. At 4400 rpm the gains are 86 whp. The torque gains through the curve are impressive. However, we do not know if the dyno was on 91 or 93 octane. We are guessing 93 was used and would like to see a separate dyno for each. The tune retails for $1500.
