The first 2-300 miles are significant. Supposedly the piston rings are seating. It is very impt to vary engine speeds (that's what _BMW_ advises in their breakin "procedures." No mention of this in Porsches "hints.")

Anyway in my 997S I shifted literally every five minutes to keep that engine speed all over the map (and under 4200). I don't think you can shift too much at the beginning (unless you're insane and doing it every ten seconds).

FWIW. Good Luck and CONGRATULATIONS!!
