I have had the M-engineering tune now for over 2 years. I love it. I finally got my son-in-law to dyno it, thanks to M-engineering's dyno mode.
My 992 C2s has Akropovics exhaust and Soul sport cats. It was a warm day so we had to let the car cool down. This is on a dynojet that has seen several thousand cars on it including many running Pikes Peak. My son-in-law has tuned about every car that you could think of tuning over the last 20 years. The dyno is very consistent.
So the numbers after cool down and with fans on the intercoolers was 527RWHP and 544RWTQ. This is the stage 1 tune on 91 octane. When the car was heat soaked, it still put down 464RWHP and I don't remember the torque numbers. Here is the dyno pic.

That's awesome on 91 octane gas. What's your elevation in Colorado? I wonder if it would make more power closer to sea level.

Elevation is around 5800ft. My son-in-law does custom tunes and has found that most tunes can be improved at this altitude. Unfortunately, M-engineering does not provide their tuning software so he cannot tune it.
Yes, we only have 91 octane pump gas here. My car is a daily driver.
Actually Stage 2 is based on whether you upgraded your cats from stock to sport (i.e 100 cell or 200 cell) or catless. The Soul sport cats are 200 cell

that is really helpful. good to see some 91 octane tunes getting good numbers.

You should log some runs and send them to M Engineering to see if they can adjust your tune. However, one huge benefit of turbocharged cars is they typically automatically increase boost at higher elevations due to the less dense oxygen in the air preserving more power than naturally aspirated cars.
Question to all of the experienced tuners and to M-Engineering… is it ever “too late” to tune a stock 992?
Like let’s say I bought a used 2020 992 that’s fully stock and has, say, 30,000 miles on it already. Would it be too late to do a stage 1 tune on that car? I’ve read that it’s always good to tune when the car is newer so that the motor “breaks in” with tuned maps, but curious if it’s ever too late.

not an experienced tuner: but as long as the maintenance on the car has been done to porsche specs, no, no worry at all. in fact, you might even be better off.
We recently tuned a 992 Carrera with 60k miles on it! There are some drivers out there

That’s awesome! Are there any pros / cons or differences in risks in tuning a new / very low mileage 992 vs. a well-maintained and well-used (30K+ miles) one?

Or pretty much the same?
Personally, I would just make sure the car is in really good shape. Tires should not be in good condition, air filters clean, all maintenance and oil changes done properly. Spark plugs replaced and gapped properly, charge pipes not leaking or cracking, brakes and brake fluid in good condition, shocks not completely shot/worn out, etc. Adding 100 hp to a car does add a decent amount of stress to it and you want the car to be as perfectly running as possible as the added power will amplify any issues in the car. If your tires are near their end of life, you will have even less traction. If your brakes are worn down, it will make it even less safe to slow your car down when you're hauling with your ECU tune, etc.
With that said, I have driven many tuned turbocharged cars up to 100K miles without any issues beyond regular maintenance and making sure all consumables are always properly maintained and replaced. I would expect the same for a Porsche.
