The fault you are getting means your Cam Tensioner has problems which it cannot compensate for by adjustment.

Driving your car with this error is inviting a major failure [sucking a valve].

I would not drive this car until you find a competent mechanic to evaluate your problem totally.

Short of running your Boxster without oil, there is not much worse then sucking a valve.

BTW - there is a TSB on this type of CEL.

What year is the Boxster.

I just noticed your name 911SC - do you remember the Carrera chain tensioner upgrade. This is telling you you are about to have one of those failures, if the CEL P code is dead on.

it's a 97 ,yes i do know about the 911sc upgrade chain tensioner,is this a common problem that most of the 97-99 got ?

No, I have heard about it a few times, and one person blew his motor because he ignored it.

Rev'd to high [subjective due to the bad tensioners] and that was it - next motor:ah:

I don't believe in dealers, but I would seek someone with a PST2. To verify the codes, or someone with a PST2.

If you send me an PM with your e mail, I will send you the TSB.
