I read with a lot of interest the thread on revving your engine and that doing the Italian Tuneup is good for the engine. I am just curious to know if any Octy or Faby owners have done so. If so, did you encounter any problems, such a interior parts shaken loose by the high RPM or just any problem that came about after the high RPM runs? So far, I have not pushed my Octy pass 3500. Has anyone redlined their engine?
