Wanted to share some updates with y'all on the GTS platform. Really liking these cars!! We had a a 2021 718 GTS show up this week for a Stage 2 calibration on our dyno in Torrance, CA. This particular car came to us with a competitor's tune that wasn't making the power these cars should be able to make. With the right calibration utilizing M-Tuner, we saw some huge increases across the board throughout the entire rev-range. M-Tuner allows the end-user (that's you) to go back to true stock at any time. You can also read and clear faults, datalog, and change maps to another octane!
PSE - with our calibrations we can set the PSE exhaust button to be truly "on" at all times when pressed. No need to buy separate controllers, your exhaust valves will stay on!
We tuned this car for several mapping configurations including 91, 93, and 100 octane.
This car was equipped with Dundon Street Headers.
Please visit our website if you'd like to purchase M-Tuner, or reach out to info@m-engineering.us / 949.444.2150.

Impressive! How does a tune like this hold up to track abuse? Is it ok/recommended? Or are there additional cooling upgrades you'd recommend?
Long term reliability needs to be there for me, especially if the car will be pushed hard. Can't wait until my car arrives and parts start going on. You guys are definitely my top pick for a tune when it comes time!
With the GTS, does the redline move from 7800 to 8000?
I'm curious about this as well!
The GTS 4.0 cars come from the factory with a 200rpm lower redline than the 718 GT4 and Spyder. I'm guessing that Porsche won't let you change the factory overrev ranges. So if you move redline up to 8K rpms, does that mean that every trip up to 7,900 or 8,000 rpms would spin the Range 1 Overrev counter?
Since you are looking at the factory coding, do you now know what the factory ranges are for Range1, Range2, Range3, etc. on the GTS 4.0 cars? Presumably it's different than those in the GT4 and Spyders, since they have a 200rpm higher redline.

We can gladly raise the rev limiter to 8000 rpms if you like.

These engines are built with a lot of headroom from Porsche, and take use and abuse very well. As long as you keep up with your factory recommended service intervals you'll have a happy car

The rev ranges are really only viewed for manual transmission cars, and are a great tool to see if a "money shift" has occurred at any point in the car. 200rpms is a small amount, and something the car can take without issue. If you have a PDK car, the coding in it won't allow you to money shift, there are safeties in place to prevent that.
I was wondering about dialing in the tune for specific modifications …
Is this included in the price (sending in data logs and getting updated calibration files, that sort of thing)
thanks!

Would be great if you could list the options available, such as exhaust flap control, auto stop/start disable, rev limiter to 8000, speed limiter removed etc?

Our Stage 2 mapping works for most aftermarket exhaust setups (headers, high flow, OAP, etc.), we will gladly look at your logs and make minor adjustments if needed. Map notes for the 718 can be found here: https://m-engineering.atlassian.net/...ibration+Notes
If you want to go the full route of a custom calibration, with remote dyno time or extensive street logging, we do offer ProTuning services that start at $1500. These are normally reserved for cars with upgrades that go beyond the typical upgrade path or have unique and exotic fuel setups, etc.

Sure thing!
Exhaust Flap Control / PSE - comes standard with M-Tuner. We have the ability in our coding to give you full "ON" control.
Auto Start/Stop disable - not currently available, we are looking into this for a future update.
Rev Limiter - upon request we can move the RPM
Speed Limiter - we remove the limiter.
Just sent in my car's info for the calibration files. I'm looking forward to this. Hoping to test it out at Thunderhill tomorrow.
One additional feature came to mind that would be incredible if you could achieve it... the ability to remove the "Oil Change Needed" warning for those of us that change our own oil based on # of track days, not miles.
If you raise the redline/fuel cut of the engine with the tune, and then later in the car's life a Porsche DME report is run on the car, will the DME show rpm overruns?
