Tuning yourself out of a warranty?

Tuning yourself out of a warranty?
I did the muffler delete and K@N Rampage C.A.I, and now I really want to do a dyno tune but don't want to affect the warranty. Does anyone know if tuning is allowed under the warranty? There is no way I will do one if it affects it. Thanks

They are correct. Basically, any little "modification" can void your warranty.
Personally, if you're looking to "fool" the stealerships these days. I would just purchase a second PCM, put it in before the tuning and get that pcm tuned. Then one day before you go to the dealership for your warranty work, just go ahead and switch them back.
One thing I did just think about though. Does anyone know where the actual odometer information stored? And would switching from PCM to PCM alter the actual milege from the displayed mileage? Something to ponder..

The Magnuson-Moss Warranty Act requires that your warranty be upheld, even if you have modifications, unless the modification itself was directly related to the defect/failure that led to the warranty claim.
A tune is "directly related" to an awful lot of stuff on the car, so it would make your warranty invalid for a lot of things, but there are also a lot of things that the warranty would still cover (body, interior, wheels, brakes, steering, suspension, and more).

Re: Tuning yourself out of a warranty?
I had a 97 Trans Am with tons of mods and the dealership had no problems with an SLP CAI, and other mods. At first they tried to negate the warranty for the EGR pointing at my JBA Longtube headers, but I pointed out GMPP sold them under warranty. They eventually did the warranty replacement.
I don't know if things have changed in the 6 year or so I've been out of this, but you used to be able to return to stock tunes with any tuner. So, return to stock, get warranty/smog check, and then go back to tune. Supposedly California was even going to start checking CHECKSUMs in the PCM to catch tunes, but I don't know if that ever passed (OBD3?)
