Default Rough idle normal? GT3 997.2

i have owned the car for more than 4 years now. I haven’t noticed that the idle was rough until my brother pointed out that to me when he first drove it just yesterday. I thought it was normal but now I’m second guessing.

Idle is not silky smooth but a bit rough. Is that normal? Car is running strong on and off track.

Please share your experience.

PS- my car has that bit of hesitation around 2400-2600 so very slightly but has been that way since I bought it. Car is well maintained with all services done as per the book.

It's normal. Race engine and all.. I'm guessing it's down to the cams.

In regards to it being hesitant, have you checked the exhaust valves performs as they should. They have an impact on torque. Else I would think air. Filter all good?

Idle is normal. Slight hesitation, I have it on my 997.2 GT and did so on my C2S before that.

+1. The idle is somewhat lumpy. Completely normal.

Could the hesitation be related to a fouled fuel filter? Dirty MAF?

May post a video recording/sound clip. The idle is uneven, but if the car develops a problem gradually, it might be hard to notice the problem.
