    SMG relearning/adaptions: 20%
    New rear diff bushes + RACP reinforcement: 30% (I did these two things together so can't rate them separately)
    Nailing filling (RF) in the tune so that the engine is responding as the SMG model expects: 50%

    Me from a few years ago would never have dared doing something like coming to a stop with foot completely off accelerator downshifting from 2nd to 1st. Now I do it pretty much without even thinking - it's smooth, accurate and reliable. Good fun.
    Just curious

    Are you modifying the SMG code based on the CSL 255 tune?
