Chipping a new vehicle in any way automatically voids any and all warranties you may have from the vehicle manufacturer...

Ignore whoever's telling you that BS! :R
"The Magnuson-Moss Warranty Act (15 U.S.C. 2302(C))

This federal law regulates warranties for the protection of consumers. The essence of the law concerning aftermarket auto parts is that a vehicle manufacturer may not condition a written or implied warranty on the consumers using parts or services which are identified by brand, trade, or corporate name (such as the vehicle maker's brand) unless the parts or service are provided free of charge. The law means that the use of an aftermarket part alone is not cause for denying the warranty. However, the law's protection does not extend to aftermarket parts in situations where such parts actually caused the damage being claimed under the warranty. Further, consumers are advised to be aware of any specific terms or conditions stated in the warranty which may result in its being voided. The law states in relevant part:

No warrantor of a consumer product may condition his written or implied warranty of such product on the consumers using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade or corporate name... (15 U.S.C. 2302(C))..."

It's the responsibility of the vehicle manufacturer (or warrantor) to prove to the satisfaction of the court that your modification caused the part failure. Your vehicle's ecm is tuned for minimal emissions, not performance, not mileage, etc. Tuning optimizes either mileage or performance, just not always both at the same time, by adjusting timing and air/fuel ratios set to provide power, but meet federal mandates to minimize emissions. If your vehicle falls within stock parameters of the tuning device, you can see performance and mileage increases. Modified engines will need a dyno-tune to precisely map their tuning device.

sorry, but MM only applies to what is needed to maintain the warranty through normal maintanance as outlined by the product mfg. E.G. oil filters, fuel filters, oil etc. it does not address modifications to the warranted item.

And BTW the quote is NOT repeat NOT the MM warranty act text. Only the second paragraph is a quote from the act. (which is pages long)

That act was passed in the 60's. This is likely an "interpretation" by a aftermarket supplier company claiming that under MM your warranty can't be voided.

What the quote isn't saying (amongst other things) is that MM clearly states that the mfg can include exclusion and conditions to the warranty that are legally valid. That is exactly what GM and ford are doing today. If you read the exclusion listed on for example the ford label near the radiator on some vehicles it clearly states addition of aftermarket tuners will void the engine and powertrain warranty. GM does similar.

So proceed with caution on tuners, and don't be suprised if at some point your vehicle gets flagged with a voided warranty in the mfg system.
