Hi Charles – Any updates on getting the factory boost gauge to read higher on our tuned cars? I see the factory GTS gauge reads 19psi, versus our 17psi factory S models, so it would appear the factory can read can higher…its just how to get there. I’m sure a low priority still for you guys, but holding onto the hope that one day I can get a re-flash that will depict the 20+ish boost from the tune. Thanks again for all the great service along the way!

In my case datalogs revealed that my car had huge boost gains from this tune. We have some damn good 93 octane here in the Midwest or something, so occasionally my PDK didn’t like what it was seeing.
I still remember how fast my 992 was after this tune. I used to do WOT’s on this back industrial road and I was like “holy smokes this is nuts”. Just so fast. I currently have 2 very fast cars in my garage by all normal standards, but my tuned 992 spoiled me. Nothing feels that fast any more, LOL
Based on my datalogging I was seeing similar boost pressures to you (~26psi, tapering down to 22). 100% agreed, the speed is unbelievable. And yet, a plaid will still go 60-130 more than 2 seconds faster. 🤯🤯

This would be killer!

Reason: for accuracy

26 psi?!?! Was that an error with the canned tune or just your car responded poorly to it? In previous posts folks have mentioned 22ish..first I’ve heard of 26. That is quite an in increase.

Not an error to my knowledge, and this is the same boost pressure @Tupper reported. [edit: searching the thread, he reported 27.8psi at one point]. My charted data logs are in post #1105, quoting here.

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.

Actually, my all time high was 27 psi when I did a WOT with the sport response button pressed
Hey guys, I wanted to post up this cool graphic data set over from Jon at Flat6 Motorsports. He took his 992 Carrera out to the track and got some great before/after time data to share with the tune. Flat6 is a dealer of ours and always carries M-Tuners ready to go!
We have lots of track junkies who run their cars out on the track as well as the street. As a reminder we also have 100 octane tunes for those who put in race gas.
The Base has a very very noticeable increase in power, I could not say the same for the S. From my reading, it looks like a lot of Base Carerra members noticed this bump. I'm not too car technical to explain why, but I experienced what everyone was saying, my base carerra was very fast after the tune and cars that I did not think I could smoke got smoked.
We've tested on the base, S and GTS. The S shows the best gains on the dyno and dragy times. The base also has great gains. The GTS comes a little more tuned up from the factory, so the gains are still there but not as significant as the S. I think all 3 are worthwhile but I think if you have an S, do the tune and add a few bolt ons, you'll be very happy with the end result in terms of power and power delivery.
We'll be testing next with the S/GTS turbos at the same track. If my P zeros make it, we'll get some lap times before we throw the Cup 2s on! Should be interesting, I'm hoping to take a few seconds off with the new turbos/power. Unfortunately, I don't have an LSD so I'm interested to see the behavior of the car on track with the new power.

definitely interested to see the outcome and your ultimate thoughts on if the upgrade is worth the cost.

I can tell you so far on the street, it's awesome. We do a lot of the GTS turbo conversions for the 991.2 Carrera but the 992 with the M-Engineering tune just seems to add that perfect amount of performance and drama to the car that makes it put a smile on the face.
We'll also be getting dynos shortly, we're still testing and logging everything. We have some S/GTS turbos in stock and will be releasing our kit once we finish our testing and get dyno figures. I'm excited to overlay the stock 992 Turbo S plots with this set-up to compare. We'll be pushing the platform more but I'm thinking the S/GTS turbo swap will be one of interest to a lot of folks. From a power standpoint, you get that OEM reliability as you're just converting the car mechanically to a S/GTS with a Stage 1 tune.

Is there a Stage 2 Dyno for C2S? The stage 2 dyno for the C4S is showing a good drop in TQ compared to the stage 1 C2S dyno. I think it's to relieve the 4wd system from over stressing.
