actually higher RPM are good, these engines fare poorly when the engine is "idling" for too long, like sitting in traffic during your intense summer heat or running while parked for too long. Also bad is when you are short shifting in an attempt to save gas or to "go easy" on the engine -- shifting at low RPMs, below 3,000. The caveat is that you should shift above 3,000 RPM once the engine is properly warmed up (by driving it at normal speeds for about 10 minutes). I'm not sure if a tip is programmed to do all this when in slushbox mode. I would always drive it in manual mode for the first 15 minutes if I had a tip.
You also want to make sure the oil never low, add oil whenever it needs a bit more.
I tell my friends that Porsches are reliable but they are not durable if you don't drive them correctly or maintain them properly. AKA...high maintenance!
