Do performance chips void Warranty?
Is this something that should be taken up w/the dealership?
If it was added, would it show up on a diagnostic if the dealership decided to run one? I spent the extra cash on the extended warranty so I don't want to mess that up.

Yes 9 out of 10 times if the dealer finds it your warranty is gone. If they hook it up to the computer it will show up if it's a downloader tuner(sct, quadzilla), if it's a run on the fly tuner (banks, edge) a good tech can still find it just harder. If you spent the extra money on the extended warrenty it's probably not a good idea.

x2 on the reprogram. Maybe not totaly "honest", but they wouldn't know you had a tuner. Unless of coarse you run a really hot tune and burn a piston or something major and the hard parts show overboost/overfueling etc.

Actually every time you reprogram the ecu it's stored it's just a matter of knowing what to look for. From what I read overboost and overfueling is stored on ecu to tell if it was higher then normal to find tuners on the duramaxs not sure about the powestroke's. On the older trucks it wasn't as bad with newer trucks it's alittle different. I know if I had there job recording higher boost and fuel levels would be the first thing I would program that would be saved.

I believe the new 6.4's have a tattle-tale that knows and logs if there has been tuning changes. The older 6.0's do not.
IIRC, (some one correct me if I'm wrong) if you disconnect the batterys after a reflash to stock settings the only thing that will show up on the ECM is that there was a 12v power loss to the computer (ie dead batterys).

Correct. Then it will clear the dead battery message once it has completed a new drive cycle. (I think 15 miles or so)

Thanks UGA33, that's even better news. I didn't know the 15 mile thing. I thought the dead battery fault code had to be cleared with a pc or whatever the dealership uses, nice that it will take care of itself.

Actually, these trucks since 1997 have a flash counter. If its been re-burned with a flash tuner, the counter will show 999. There is no way to get a custom tune without ford finding it, whether you remove it or not. If that counter shows more flashes than what ford has in Oasis, you're SOL.

There are things that will show up that can conclusively show that there was a power enhancer on the truck. Disconnecting the batteries will not clear it. Some 6.0L trucks had this, the earliest ones did not.

I understood you touch it, they can find out as soon as the dealer plugs into it. With the pissing match with IH and the tight money- they will drop your warranty like a used rubber if they can find a legit way to do so.

Hmmm, maybe a little more tricky than I thought. I guess the safest bet will be to go to the dealer and be up-front with them on what I can and can't do. To many things that can go wrong with an 08 I don't want to take a chance on mucking up the warranty.
