One thing I've not seen/heard discussed with the Upsolute Chip is what effect it may have on emissions, if any. I know for WMichaels that is not an issue because in that part of Virginia they're not doing regular emissions testing.

David Burns, doesn't Va do emissions testing in your area of Virginia? If so, you may also not want to fool around too much with a less restrictive cat if it in anyway compromises the emissions.

James...I'm not sure the thought that an aftermarket mod does not effect warranty is as black/white/absolute as you suggest.

Surely, if your car stops running and all you've done is change your shocks, you'd be right.

Messing with the ECU/chip, however, can have a theoretical and real impact on engine mapping and performance, and any number of mechanical failures could be tied to that.

Saying the manufacturer has the burden of proof isn't exactly right either, I would think. You come in for a repair, they say no, the mod created the problem.

Ball's now in YOUR court. YOU have to take the next step and prove that your mod did not.

The dealer holds all the cards in the warranty situation. He just has to sit there and do nothing until the car owner presses the case.
