Odd Boxster Sound?

That's kind of odd. Porsche says don't lug the engine and that's exactly what the auto tranny does sometimes? I thought that tip transmission was supposed to be smarter than the average guy.

Adam,

If I am accerelating very slowly, the auto shift points will sometimes come too early.

BTW - Why would there be an issue with running the engine in sub 1500 RPM range? Idle is sub 1K, starting in 1st or 2nd spends a lot of time <1500RPM. I dont get it!

It's ok to spend some time under 1,500 rpm...we all have to do that like when taking off or going around a curve, but you don't want to spend an excessive amount of time there. What Porsche says not to do is lug the engine. Meaning don't drive it 40mph in 5th or 6th gear for example. There is very little load on the engine at idle so that would not apply. I'm not sure why exactly Porsche says to avoid this, maybe someone else on here can shed some light on it.
