Now that it has been established that there is practically no instance where a reasonable high end ECU flash upgrade has caused damage to a 992 or
has affected the warrenty,
What problems will there be in selling the car, both in and out of the warrenty period ?
Will buyers avoid such cars ?
Will this car be desired by collectors ?
How much financially will be lost from a stock version of the same car ?

The best thing to do is return the car to stock when you sell it. That’s why you should also hold onto all of your original parts — exhaust, cats, etc. When it comes time to sell the car, you re-install the original stuff. You then sell your used performance upgrades separately on RennList or EBay.

As long as there is nothing wrong with the car, sell or trade, and encourage a PDI/PPI. A previously tuned car returned to stock wouldn't matter to most buyers or sellers. I know at least 5 people who have either tuned, or bought tuned cars that the manufacturer had no problem taking in trade and CPO'ing, so long as they were returned to stock.

Food for thought (long thread, but I quoted the final outcome):

https://www.audizine.com/forum/showt...ence-Tuned-TD1

"Sorry I was MIA for so long... I did a lot to try to work with the dealer and AoA. I had a friend that was a lawyer try to deal with them, and was ultimately rejected. Despite my proof from APR that it was tuned prior to my purchase, they say it must have been tuned back to stock prior to the CPO, and then I re-tuned it later. I reached out to a legal firm, but since my supposed CPO warranty was almost up, and I was so far "only" out about $3k in repairs that should have been covered, they didn't think it was worth their while.

I thought by buying a "certified" car from a premium brand that I would would be pretty safe. My bad.... Audi does not stand by the consumer at all, and in fact will actively fight against them when the dealer does wrong. I actually loved the car, but I will never own another Audi, and will vocally recommend that anyone I meet never buy one as well.

Just today, I traded it in for a Kia Stinger GT2 (Audi to Kia, I know, right?), and will sleep a lot more soundly knowing that I have 10 years before I have to worry about paying for another powertrain issue.

Sadly, my Audi experience ended up being like I hear it is for a boat owner... Your happiest days are the one you bought it, and the one you sold it. Definitely not how I expected it to play out. "

CPO is a joke. They CPO modified, tuned and crashed cars without returning to stock, no hesitation.

but...but...they go through a checklist! Have you forgotten about the CHECKLIST??

CPO = “Yep, it was definitely pre-owned.”

Last couple times I traded in one of my BMW M cars, the dealer asked me to sign something saying I did not touch the ECU. I suspect this will become common practice at all dealers soon enough. I also have seen numerous BMW engines blow or hub cranks spun due to tunes and even though the owners attempted to fraud BMW by flashing it back to stock. They got caught by BWM who checked out all the logs in the black box and determined it was tuned or altered. BMW would also monitor bimmerpost.com and use anything they found the owner saying on that forum against them. Im sure some of us came from bimmerpost and have seen or heard about this too.

I also think we dont see much of that here YET due to the fact that the 911's are not as common on the road in masses. And because 991.2 turbo motors are the ones that really got tune offerings going for Porsche. Lets see how long these 991.2 or 992 motors last with 100HP added to them via a tune on 91 gas and 40-60K in miles. I'm willing to bet we will see a lot more issues. Maybe we wont! But I'm guessing we will.

The motors are **** if they can't run a hundred more horsepower.

detansinn

It’s not about the “horsepower”. It’s the air fuel ratio stuff — running too lean/hot.

I do have to say that this series of separate tuning related posts from @malibu515 reminds me of this sketch from The Onion...😜🤣

phaser

Yeah, I know that stuff. I have tuned many vehicles myself and believe me there is quite a bit more to it than afrs.
The point is that these motors are stout with forged pistons, connecting rods etc. A 100 HP bump with a calibration change is not going to be a problem.
Ford has dealer installed PD supercharger packages that add over 200 horsepower to their N/A 5.0L Coyote motors and they warranty them.
+100 HP on a factory turbocharged 992 engine is a jump shot.

Simple answer: I'll never buy a tuned car,
and to flash a car back to stock without notifying new owner is disingenuous

I do think it's interesting that Porsche felt it necessary to reinforce the Turbo/S PDK to better handle the higher torque of the TT/S models.

I suspect they are super conservative with the TT/S which is traditionally bulletproof.

You've got to be chomping at the bit waiting for your '21 TTS. I envy you my friend.
