I honestly don't know what's different now other than the way it feels. When you go to modify a setting such as the shift firmness it is at stock, but you never really know what stock is. The biggest difference between when I originally got it and now is the additions they have made to the adjustable parameters. There are a lot! It would be interesting to have someone get a custom tune and datalog their passes in the 1/4. Then another person datalog their 1/4 passes running on a canned tune to visually compare the differences.
