They have done some eletronic and software mods for shure. That often means that you don't get an DTC because the DME/system gets fooled by intention.

What transmission do you have in the car? AT, MT6, MT5? If AT, that could also cause problems.

no no,
lets be clear.

99 everything, including the maf (not a 987 maf). Think of the motor as an upsized 2.5L with a intake manifold resonance flap.

The SIZE of the maf sampling tube has been increased, but that is adjusted with maf scaling.

Tranny is a MT 5 speed.

The car runs perfectly fine for 30 minutes, and runs perfectly fine up to 6000rpm after 30 minutes, and then runs fine after shutting it off for another 30 min.


If the car didn't run, or ran crappy from minute one, Id think a lot of points are valid.

Will review that document porsche-eh.

Thanks everyone for your comments.

Just to be clear, is this 30 minutes exactly or around 30 minutes? When you say shut it off and it runs fine, you mean you can just cycle the key off and right back on and everything is fine or you have to shut it off for let's say a minute or 10 or what?
