Thanks for the great info.!

Guys, 100% I recommend.
I ordered the Stage 2 tune for my 992 CS.
The Tune by itself is amazing! and their support is just on point.

TYVM.

Now put an E85 tune on it, filler up and really see what amazing is !

I was doing some pills last night on the highway, and the GTS is either really smooth, or it’s not fast up top. I’m so used to my ‘94 Supra BPU+ and the sequential power delivery that I can’t give a fair butt dyno reading.

stop taking pills while driving. 😂

What kind of pills were you doing? Seriously though it’s the sensation of speed in the 911 that makes you think that. On other cars it starts feeling out of sorts at the top end and in triple digits. The 911 is in its element and it’s like butter at the top end. With the way it sits you can’t feel the difference between 50 and 150 and on top of that there is no unusual noise, vibration, or sense that the car is reaching a limit of any sorts.

Ya’ll are funny, I meant pulls 😂

It is true, you really can’t feel 50-100. In my Supra, it’s pretty violent, and you definitely it.

I think you nailed it. The fact that the 911 doesn't "struggle" mechanically speaking makes these pulls feel maybe a bit too smooth, no drama. But the car is definitely fast. I went with M Tuner Stage 1, and while the improvements are definitely noticeable, it's still very damn smooth. I've been in other tuned cars, some with many fewer HP than my current car, and they felt much faster. I think that's mainly because the 911 is so well put together as a whole (steering, suspension, etc.) compared to other cars where each element is engineered on its own.

There is no doubt the 992 pulls very smoothly and more so than any car I've had in the past. With that said, I don't think the smoothness makes the car feel slow by any means. In fact, the 992 accelerates better than any RWD car I've ever had becuse of the massive rear grip that just allows you to put almost all the power down, even when tuned. It feels like you're being catapulted or shot out of a slingshot whereas other high HP RWD cars I've driven struggle for traction, feels violent, but you're not really going anywhere due to tires just spinning out.

Left: IAT (°C), Boost (psi). Right: RPMs. Three runs.

Here's a fun chart from my data logging escapade today. Three runs, two to the top of 4th and the last only to 3rd. Timings are being pulled pretty aggressively so I'm looking into whether I should dip down to the 91 octane map or do something else to keep things safe and reliable. IATs well above 50c isn't ideal so the best solution is probably an intercooler, but I'm not willing to commit to that yet; the car is plenty fast, i have no need for more. assuming I'm calculating correctly, boost pressure peaks at 26.7psi and tapers down to 22 on the best run, and 20.5 on the worst run. Apparently the peak boost is 18.6 on stock... 😅

Here's the less-fun chart showing timing being pulled on each run.

It only gets worse as IAT goes up. Either go with intercooler mod which will delay but not eliminate timing being pulled or be happy with 50 hp gain.

How did you retrieve this data if you don't mind me asking? And do you have any tune?

zachr

I got this by data logging using the M Engineering dongle and software. It will data log into CSVs, which I moved into Google Sheets and charted to visualize easily.

I know this will sound lame, I drove a 2022 Turbo S over the weekend and I wasn’t super impressed compared to my 2021 C4S with m engineering stage 2 tune (93 Oct with Akra exhaust). Yes I know in a 0-60 I don’t stand a chance against the turbo S, but seriously it didn’t feel that much different compared to mine.

Tupper

I haven't driven a Turbo S, but the M tune does add a lot of power, particularly on 93 octane and if you have sports cats and an exhaust. I will never know how much HP was ultimately added to my car, but it had to have been well over 100
