Pinking type noise on GT4RS

[Rogere]

Hi there. Looking for advice, or shared experiences.
Over the past couple of months I’ve become increasingly aware of a concerning sound when I accelerate gently away from a junction, roundabout etc from low speed. It sounds very much like pinking, just as we had back in the old days….long before super impressive ignition systems.
I always use super unleaded and the car has now covered 13,000 miles.
The sound isn’t there under hard acceleration, but the you don’t hear much under hard acceleration!
Anyone else had this?
Many thanks Roger

The injectors are pretty noisy on these engines, could it be that? It changes hugely with light-ish throttle position. Gemini said there is a Porsche advisory that says its normal

I have a similar sound on my 997.1, just like pinking but for a split second only. Mine happens when I heal and toe and blip the throttle aggressively.
Took it to Addspeed who found a leak on the intake manifold. The ecu is currently in re learning mode but I still have the noise a bit.
