I may be wrong here, but I thought the purpose of the break-in period on the car was to allow the piston rings to set properly with the Cylinder walls. Now since you did not replace them at all, then they should not need to be broken in right?

(Someone please let me know if I'm wrong)

Although personally I would still take it easy for the first 500-1000 miles or so to make sure it is all working fine.

When I broke in my newly built motor I did it the mototune way and it seems to have worked fine.
