Main Question is....What is really the Average Whp on M3 E9X???
As you're in Europe I'm assuming you used 95 RON fuel - you really want to be using 98 RON at a minimum on this type of car.
Fill it up with 98 RON, drive it for a day and then dyno it again, I wouldn't be surprised to see a 10-15WHP gain...
