READ ANSWERDoes anyone have experience tuning PASM shock dampers with DSC Sport Controller?
Monday 02/23/2026 | 2016 | Cayman GTS | Suspension
I just installed the v3 DSC Sport Controller with the default settings for 981 GTS with PDK and PASM. I’ve used it for one AutoX event, and it felt fine. However, I’ve read that the default tuning file can be improved for AutoX. Does anyone have experience using this controller and adjusting the settings for AutoX or similar use?

Sunday 02/22/2026 | 2010 | Boxster | Interior/Upholstery
Does anyone know how to remove the horizontal trim strips (in Volcano Grey) so that I can paint them? They run the length of the dash from door to door. There are a total of 6: two short ones (2-3") on either side of the steering wheel, one above the radio, one that functions as the cupholder door, and two short ones flanking it. I'm pretty sure the cupholder door is straightforward but the total of 5 other ones look like they have tabs, and a male plugs. i don't want to break them ($30 ...

I plan on getting both PDK oils drained and replaced, but should the pan with integral metal filter also be replaced? Thank you. My dealer is recommending fluids only.

READ ANSWERTicking at idle in 987.1 Boxster S with ~113k miles
Thursday 02/12/2026 | 2005 | Boxster S | Engine
My car ticks at idle. If I give it just enough gas to get above 850 - 900 RPM, the ticking sound goes away. I don't find that I'm burning oil, I've had the lifters and clutch replaced, and the car otherwise seems to run strong. I had an engine oil analysis done (I don't know who the mechanic sent it to though) and they said there was no metal in the oil (did they test for aluminum? I don't know). Any thoughts on what could be causing the ticking? Thanks, Da ...

I purchased a 2004 Boxter S with a damaged immobilizer. But the previous owner lost the damaged immobilizer so I don't have the chip from it. A Porsche parts shop has a set ECU, DME, immobilizer and key from a 996.2 C4 and wondering if this will work? The ECU has the same numbers on both the Boxter and 996.
