I ran a 7:20 on Nordschleife right outta the gate with that tune. Which for me is not bad.
👍 No real bouncing issues (as long as you set up correctly for the bumps). And it beat my e46 Works car record by 4 seconds. The tune for the M3 is still evolving, but it's better than it was. I'm not sure if it's EVER going to feel as tight as the Porsche. Here is my tuning for the M3 so far...

It's set up primarily for the Nordschleife. I shorten the gears a bit for smaller tracks.
Update: This tune seems much more controllable than previously and less suseptible to bounce. The car still seems wildly short on traction and downforce but there doesn't seem to be much more I can do to improve it. Hopefully wiser heads than mine can fine tune this.
