Default Would you buy a car that been "tuned"

Recently bought cars for myself and the wife. Went new this time but have bought CPO in the past. While researching cars (VW and Audi) for purchase I became aware of how popular "tuning" is on them. Actually it appears to be quite widespread among many brands.

While "tuning" does increase performance it does so at the expense of reliability and warranty coverage. Used to be that you could have your ecu flashed back to stock or remove a "piggyback" tuner prior to taking a car in for dealer service but that will not work on VW/Audi cars any more. When a VW/Audi is brought in for a major problem like a blown engine or transmission the dealer has to connect the car to the VW/Audi electronic diagnostic system which can detect the presence of a current or previous tune, even if the ecu has been flashed back to stock or the piggyback unit removed. There are non resettable registers in the ecu that can tell how many times the ecu has been flashed. If the count includes non authorized flashes or if the system logs show the engine running outside of normal parameters due to an ecu or piggyback tune the car is tagged "TD1" by and the warranty is made invalid.

Obviously this could get expensive fast. Problem is I have read of people claiming to have purchased a CPO car that later turned out to be tagged "TD1". Scary part is that tuning is incredibly popular, Many people think nothing of selling, trading in or even turning in a leased without revealing that they have been tuned.

Would you buy a CPO/used car that had been tuned? I would not.

I wonder if you can get it reflashed at the dealer back to stock and remain under warranty CPO?

The damage would have been done by then.

I would not buy a CPO unless I had a written guarantee from the dealers manager that the card was not and never had been tuned. Even then I would be uneasy about it.

If you wanted a tuned car.

The same can be said of diesel trucks these days. How many THT members have their tow rigs "tuned"? Fact of the matter is manufacturers are leaving performance on the table on purpose. Outboard motors as well.

Case and point. Would you own a hellcat or demon? I own an srt8 charger and if I put a super charger on my car it may would fall under the "tuned" category. Knowing that would you buy my car? If u would own the hellcat but not my car is that not biased or is strictly based on warranty? My BMW motorcycle has full titanium exhaust and has an ECU flash amongst other performance parts. ITS STILL UNDER FACTORY WARRANTY but is def "tuned".

For me it would all be has it been maintained, well cared for, and or hot roded or not.

brings my thoughts elsewhere...u buy a CPO for the warranty assurance so to speak....would any dealer make a "tuned" car CPO? I KNOW ford can tell now on their trucks that u have had a tune even if it's no longer present and that is an immediate VOID

Are you sure that your Charger is still covered by the warranty?
Many VW/Audi owners didn't find out that their tuned cars were "TD1" until they showed up at the dealer with a blown transmission or engine.
You might not know until you blew an engine or transmission.

No. Definately not an Audi or Dodge as mentioned.
If it is otherwise stock and owned by a "normal" guy- maybe
wheels stanced, after market parts stickers, loud exhaust, riced up looking HECK no

Possibly. I'm not sure is BMW still allows Dinan parts to be on cars and not void warranties.

I would not buy a "tuned" car.

I had a handheld SuperChips tuner for a G8 GT but the tune was easily reversible so when I traded the car, I deleted the tune and sold the tuner.

my charger doesn't have the super charger. It's been a thought. My car is an 07 warranty has long been gone. However it is a numbered car and thus the reason why it remains stock. Just a thought as to rather or not tuning does damage.

Depends on use on "why" car was tuned. I've tuned cars to make annoying factory settings go away- with ZERO performance upgrades. If they've done a bunch of bolt ons-exhaust- tunes- I'd probably avoid that car as most of the guys that go that route are Auto Cross- wanna be racers and car will be rode hard.

interesting info ... I can't speak on the car but on my bike I had to use factory approved parts and they had to be installed by a dealer to keep my warranty

No chance. 99% of people who add performance parts or tunes to their vehicles do it for one reason. To make it faster. I have no desire to buy something someone else has abused for X number of miles. I want no part of that.

With the exception of something like a weekend only car previously owned by an old guy, hell no. My uncle is 72-73 and has had his share of tuned stuff, but he is more into showing them than romping on them on any frequent basis. Anything that was tuned and a daily frequent driver, or that I intended to use as such, not a chance.

I don’t see tuning as affecting reliability unless you go with someone non reputable. Given the right vehicle for the right price, I likely would purchase a “tuned” vehicle especially if it was nearing the end of its warranty. Saves me money cause I’d likely do it anyway.

That's how it worked with BMW and Dinan. Certain dealers were allowed to install the parts and it didn't void warranties.

I would not hesitate to "tune" a car/truck and not be terribly concerned about the warranty. But if you're buying a used vehicle and warranty is an issue then I would go the CPO and leave it alone.

It depends, if I was buying a 'fun' car I'd venture to say I'd be more prone to buying a car with work done and documented by a reputable shop. If I was buying a DD, I'd buy new or as close to new as possible (CPO).

This guy claims his CPO Audi was tuned before he got it:
