This is very simple.

If warranty of your vehicle is a primary concern, tuning may not be for you.

That being said, the uninstall files provided with M-Tuner take you back to a true stock and we have yet to run into any issues with anyone taking their cars into the dealer. If you enjoy modifying your 911, like to party, and like fast(er) cars, M-Tuner may be for you then.

Ok, so you have no proof Porsche does this?

Thought so.

Also, as described by the tuner, they are capturing an image of the memory and replacing that image. Any counter saved in that memory would have been restored to the prior value.

Just like hooking up with a crack ***** in Vegas, tuning your car is a personal choice. If you are worried about warranty, don’t do it, but also, don’t try to save us from ourselves. We know what we are doing and the risks involved. I bought the car knowing I would tune it. See ya behind me…..

I sure can agree with both statements and its simple as you said. If you are okay with the fact your warranty may be voided - go for it. My previous tuner also claimed they had never any issues with 1000's of tuned cars...until I experienced it first hand. Also, the talk about dealers covering warranty for tuned cars - that would be great, hope there is no fine print. My AMG dealer said the same about downpipes, tunes etc....until something broke they could not fix on there own and needed corporate support, that is where it all ended.

Epic response! Just outstanding!

Quick question - and not to take anything away from you or your product as in my decades of being on different car enthusiast boards, M Engineering seems to have set the high bar standard for both the quality of their tune and amazing customer service. So now the question: if PNA or the dealer wanted to look for the tune (and no reason why they would if all looks up an up), could they not look at the history of the parameters that the car was running at to determine that the car could not have operated at those levels without a tune? Again, this is just a question for my education and not a challenge to the product as I fully agree that anyone overly concerned about the warranty probably should not be getting a tune.

I’m starting to benchmark my stock (no tune, no down pipe, stock exhaust) 992S, RWD, before I do the tune…, so went out to our local airport (there is a infrequently used access road that runs parallel to one of the runways).

I wanted to measure 0-60, 1/8 mi and 1/4 mile, but unfortunately, at the longer distances, I was on a stretch of the road that had a slight upgrade, which produced: “invalid run”.

Nevertheless, I was able to get two valid runs to 60mph. First was 3.22 sec and the second was at 3.11 sec. Road was dry (but not very smooth/in good condition), with temp at 70F. I’m pretty happy with the runs, and is what I see in most of the reviews, but think on a smoother road, and cooler, etc, I can do better. Quickest time I have seen for this car is 2.9x sec.

With the tune, and 150+ more hp, I would think times approach 2.6-2.7 sec.? Anybody with an M-Tune done any testing?

ECU's do not store datalogs or parameters of sensors after you revert to a stock file, everything is reset including other modules.

Cool! Thanks.

Thank you Charles. For me, the issue is “WHEN”, not “IF”. The warranty will eventually expire so that issue resolves itself sooner or later. Between now and then, I will gradually add Soul headers, Soul sport cats and a tune. Just a question of timing ……….and a sufficient bank account to do it.

Correct Peter. The warranty is not administered by the dealer. It is administered by Porsche NA. Porsche NA and the individual dealer franchises are separate and distinct legal entities. The dealer cannot bind Porsche NA to anything. However, having the Porsche dealer in your corner and advocating strongly on your behalf with Porsche NA is a substantial plus.

Still running the tune? Any issues? Any warranty issues? Any recommendations on best tune?

it is my opinion that any tune will need an upgrade to the intercooler system because the stock system can’t keep up with the extra heat generated from the increased boost and turbine speed. Any dyno gains will be short lived in real world driving.

I think it really depends on where you live, whether you track your car, how you drive, etc. I have not run into any issues with heat soak driving my tuned 992S here in hot as ***** AZ even when temps are consistently 100-110+. If you don’t track your car, it is extremely rare you will be driving your car hard enough to cause heat soak. These cars are insanely fast and even more so tuned. If you’re cruising at 40 mph, 3 seconds of foot to the floor acceleration on surface streets will land you in jail. 10 seconds of hard acceleration on the fwy will get you to over 150 mph. Honestly, none of us should be overtaxing the stock intercooler during real world driving, unless your real world driving includes tracking the car and/or driving in autocross events or running 1/4 mi drag runs or high speed mile long events.

While not the same car, I noticed the same thing with my tuned M3. The stock intercooler was remarkably effective in the hot summers here in AZ and tests of aftermarket intercoolers showed them to be less effective or marginally better. I replaced mine with an aftermarket unit only after my stock one started leaking.

I guess you are right. I usually have my foot to the floor more than 3 seconds. I can feel the power go away after the second or third hard pull. I agree with you that occasional acceleration will not heat soak the intercoolers, Spirited driving for more than a few minutes will, at least in hot and humid Florida!
