GIAC finally releases .2 GTS tuning
They posted it on the GIAC TUNING IG page yesterday. The .2 GTS ECU has finally been cracked.
Thoughts? Yes? No? Maybe? Would you? Pros/Cons?
They require you to ship your ECU to them, which they flash and send back to you.
Cost is 2200USD (I have inquired).
You can swipe through the 3-4 pics to see charts/graphs.... More info below.
Discuss.

No thanks, the peak boost with the GTS turbos is already 22 PSI for a peak effective compression ratio of 25:1 (98RON/AKI93)
I believe the 992.1 GTS will have around 470HP as per Panorama.

I'm not overly concerned with voiding my warranty. I've spoken with my SA and a few other people in the dealership about the tune and, at least in my area, they seem to be ok qith it. There's a huge shift in the industry position regarding tuning and software. Hell the MB dealer that I drove the AMG GTS at when I was deciding between to two cars was a RennTech dealer and installer. The RennTech tune doesnt come with a special warranty, so you tell me how concerned that dealer was with tuned cars. I think its down to the dealers position on it. My M5 is tuned and has been since I bought it, 20 trips to the dealer, no issues.
With the Porsche, at least at my dealership, as long as its a legit outfit, i.e. COBB, they dont seem to care. My SA said they have lots of cars come through with a tunes, its never been an issue.
I'm definitely tuning, I just want the ability to flash it stock before visits, which unfortunately is GIAC's biggest downfall.

What if your car ls leased and you decide to tune it?
I guess one could flash back to stock before the lease is up....but what if they randomly find out ECU is tuned when you went in for something random like a recall or software update etc...
What could they say to you..?
So many variables.... but man, that car would be a monster w/ over 500

If you think Porsche doesn't care, give them a call and ask them, or ask the tune vendor to give you a written statement signed by an officer of the company, duly authorized to make such commitments, that they will pay for any warranty claim denied by Porsche.

With what you said why are you wanting to be able to flash it back to stock for dealer visits then?

I can’t speak for ///M3THOD, but back when I had a Macan I had a Cobb tune on it. All I can say is WOW regarding the performance! Anyway the Service Managsr knew about it because I told him, and the Tech who always works on my P-cars actually recommended Cobb over Racechip which is a piggy back system. So the dealer was OK with it; everyone was on the same page. Having said that, if there was a Porsche ecu mandatory update while the car was in for service, whatever was on the ecu would be overwritten by the update. So every time I took my car in for service, I put the factory tune back on. Wasn’t trying to hide anything, but didn’t want my Cobb tune overwritten either.

My M5 had superficial light damage done to the front fender and required bodywork. I didn’t put the car back to stock when I dropped it for bodywork and when I came to pick the car up 2 weeks later it the dash looked like a Christmas tree and it would barely drive.
The bodyshop had, as a courtesy, tried to clear codes and update it, which made an absolute mess of my tune. It ended up requiring me to Uber home to pickup my laptop, plug it into the OBD2 port and finally get on the phone for 2 hours to troubleshoot.
