I mean those same points can be directly applied to your first response in this thread where you just started talking about a tune for the cars pushing them above stock power and then comparing GTS stock power to 450hp. Literally noone was talking about that, people were only ever talking about the difference between the stock GTS and stock GT4 and how a tune brings the GTS engine up to a stock GT4 level.

And yeah sarcasm is hard to detect online when it's all text. i dont know you as a person, i dont know how you talk normally. I can only assume you are being serious because this is the first time i've conversed with you. How do you know i wasnt being sarcastic in my comment to you? You dont and you responded with the assumption that i was being serious. But hey it's all good man. Theres no need to be hostile online, we're all here trying to enjoy the cars that we love. Whats wrong with that?

Hey Joe — knock it off. Who the heck do you think you are? Your attitude is completely unacceptable.

Back on topic. Joe — knock it off. Period.

Extra ponies show up at the top of the rev band, where many people like to live with sport cars like the GT4.

My F87C flattened out at the top of the rev band. BMW added 40+hp in the F87CS and it is VERY noticeable; pulls hard all the way to red line.

Adding Dundon headers/OAPs added some appreciably significant ponies. How many ponies? Dundon claims 30hp increase, but I only have my butt dyno to offer as verification.

Either way, an extra 20 ponies would not compel me to get a GT4 over a GTS – and vice versa – given all the other factors that go into choosing one over the other . . . not the least of which is price.

I picked up the sarcasm - but I'm British.
Also, definitely detecting some Clarkson in your above statement...

I appreciate everyone’s input. But now, let’s all play nice!

I assumed it was software related. I also assume that if you mess with that and have an engine related warranty issue that Porsche will surely put the blame on the owner and deny coverage.

please elaborate

Yes, you significantly increase your risk of being denied a warranty claim if the car is tuned. Especially if the part that fails is directly connected to the aftermarket part/tune.

He is saying that while a stock GTS has 20hp less than a stock GT4, that a tuned GTS has more power than a stock GT4.

Flash the engine to stock and they can't say much - but its transmission related failures that are more likely to come from the tune and they can deny coverage on that too.

If a major drivetrain failure occurs under warranty, and PCNA has to get involved, you will almost certainly be denied the claim based on the tune. Full readouts will show flash counting, and or parameters which were tampered with that were not Porsche Certified or performed by (dont let the tuners fool you that these cant be traced). Though I have not seen any reports of failures due to a tune on this platform, you have to accept the risk that a failure, even if not known that the route cause was due to the tune, will run a high chance of a denied claim; even if a failure falls under a "well known issue". Having a good relationship with your SA/SM, especially if they're mod friendly goes a long way for claims (even if not tune/drivetrain related).

I have tuned most of my sports cars in the past, even my S2000(NA), with no issues to date. I just dont see the point at this time (wish the case was different) to tune a NA engine with little bang for you $$$$.... now if these knucklehead tuners priced their tunes according to other platforms.. to the range of half-1/3rd the price as most of the other cars they tune (Porsche), I might have already been tuned. I currently refuse to pay the the 718 4.0 tax.

Why would anyone try to hide a tune by ‘flashing it back’?Porsche produces an impeccably tuned machine and provides a warranty to back their product.

If an owner decides to alter the product Porsche produces and warranties, why would that owner think it is on Porsche to cover the cost of failure?

Trying to ‘hide’ the tune is, at best, disingenuous. If one modifies their vehicle, they need to own it. Do not try to ‘hide’ it or hold Porsche responsible for failure.

These acts typically stem from the retailers of the tunes.
You will hear them say over and over and over, and document "Just remove the tune before you take your car in for service, and all will be good" . Most people think this verbiage is their get out of jail free card in the event of some sort of failure. IF this were true, all tuners would back their products with their own warranty - havent seen this without a ton of fine print, which was written not to protect the warranty holder, but the issuer.

I told the (had to) BMW SA that I had tuned my car, only for the reason that I did not want any updates performed that were not deemed necessary, as any updates would have stripped the tune from the car, and I didnt want to keep flashing.

Whole heartedly agree with you. Trying to hide a modification to get a warranty repair is unethical behavior in my book as well.

BabyNSX

I NEVER try to hide the modifications I make to my cars from the dealership. There is zero value in doing so as it completely erodes trust which is your most important currency when things go south. My car is likely making 50+ more WHP than stock and I realize there is non-zero risk in squeezing more power from an already capable engine. I don't hide this fact from the dealership and the SAs have a blast when I hand them the keys and they take it for a rip.

And yeah, with a simple ECU flash with the Accessport you can have a GTS that will generate more HP than a stock GT4 - that was my point.

Rather than hide from dealers any engine tune, the trick is to associate with an enthusiast factory authorized dealer that embraces tunes and says “don’t worry about it” when it comes to warranty work. There are many enthusiast dealers like this who would have your back and on the other hand there are many suit and tie, rigid, stiff dealers who consider tuning a crime. It just depends on location.
