Forget HP gains in the USA, except for canyon runs. Torque is far more important in typical American driving. The X51 Power Kit gives an extra 10% increase in torque and drivabilty. That is significant. And my X51 upgrade is costing me a lot less than the $10k mentioned. But i shopped nationwide and negotiated my total installed cost with the best parts vortices I found. If my C2S were nearing the end of its warranty and these third party mods had 4-5 years successful experience in these 991.2 911S, i might look at alternatives. But with 46 months remaining, and not a lot of experience presently out there, I'm not going to mess around with this risk.

If i worked for a growing tech company, and the Company stock in my plan was already worth $Millions, i might be more of a risk taker. But i never had that luxury. I had to earn and save and invest for 40 years to get to the point where i can have the Porsches i want. My early Porsches were all 4 cylinders, when what I really wanted was a 911. Maybe this is why I'm cautious about modding a new 991.2 like like what is being discussed here.

There is no way you're getting a power kit installed on a 991.1 for under 12K 10K is aggressive for the cost of just the kit. The 991.2 on the other hand is significantly less involved.

Better to lose weight than try aftermarket HP gains. Out engineering German Porsche engineers is a slippery slope. Add the low weight battery, replace your seats with 4 ways, ditch the back seat. How fast you wanna go ?

Wrong. Read the act.

Don't forget lighter aftermarket wheels. HREs are generally ~2 lbs lighter per corner than stock.

The exhaust is the only one of those I would feel comfortable doing and still keeping your warranty on your engine and transmission. The air filter and plenum could always have the risk of warranty issues if you had an engine issue, which is very uncommon with these cars. The tune is definitely going to cause issues with warranty. On an NA car, I would avoid a tune.

I've read it and the above is an accurate statement of the act, copied here so you can read it (relevant part in bold). It states that the burden is on the warrantor (Porsche) to prove that the consumer caused the defect, malfunction, or failure.

That said, I agree that in practice fighting Porsche is a losing battle. Porsche will fly in the engineer from Germany who designed the engine, and the engineer will say the mod caused the problem. That would discharge Porsche's burden of proof, at which point the burden shifts to you to prove that Porsche's engineer is wrong. Good luck with that.

The act was passed to protect consumers from tie-in practices (where a manufacturer says it won't repair a problem because you didn't use its approved parts). While the act applies to the mods scenario, that would be a long protracted battle that you may not win.

15 U.S. Code § 2304 - Federal minimum standards for warranties

(a) Remedies under written warranty; duration of implied warranty; exclusion or limitation on consequential damages for breach of written or implied warranty; election of refund or replacementIn order for a warrantor warranting a consumer product by means of a written warranty to meet the Federal minimum standards for warranty—
(1) such warrantor must as a minimum remedy such consumer product within a reasonable time and without charge, in the case of a defect, malfunction, or failure to conform with such written warranty;
(2) notwithstanding section 2308(b) of this title, such warrantor may not impose any limitation on the duration of any implied warranty on the product;
(3) such warrantor may not exclude or limit consequential damages for breach of any written or implied warranty on such product, unless such exclusion or limitation conspicuously appears on the face of the warranty; and
(4) if the product (or a component part thereof) contains a defect or malfunction after a reasonable number of attempts by the warrantor to remedy defects or malfunctions in such product, such warrantor must permit the consumer to elect either a refund for, or replacement without charge of, such product or part (as the case may be). The Commission may by rule specify for purposes of this paragraph, what constitutes a reasonable number of attempts to remedy particular kinds of defects or malfunctions under different circumstances. If the warrantor replaces a component part of a consumer product, such replacement shall include installing the part in the product without charge.

(b) Duties and conditions imposed on consumer by warrantor
(1) In fulfilling the duties under subsection (a) respecting a written warranty, the warrantor shall not impose any duty other than notification upon any consumer as a condition of securing remedy of any consumer product which malfunctions, is defective, or does not conform to the written warranty, unless the warrantor has demonstrated in a rulemaking proceeding, or can demonstrate in an administrative or judicial enforcement proceeding (including private enforcement), or in an informal dispute settlement proceeding, that such a duty is reasonable.
(2) Notwithstanding paragraph (1), a warrantor may require, as a condition to replacement of, or refund for, any consumer product under subsection (a), that such consumer product shall be made available to the warrantor free and clear of liens and other encumbrances, except as otherwise provided by rule or order of the Commission in cases in which such a requirement would not be practicable.
(3) The Commission may, by rule define in detail the duties set forth in subsection (a) of this section and the applicability of such duties to warrantors of different categories of consumer products with “full (statement of duration)” warranties.
(4) The duties under subsection (a) extend from the warrantor to each person who is a consumer with respect to the consumer product.

(c) Waiver of standards
The performance of the duties under subsection (a) shall not be required of the warrantor if he can show that the defect, malfunction, or failure of any warranted consumer product to conform with a written warranty, was caused by damage (not resulting from defect or malfunction) while in the possession of the consumer, or unreasonable use (including failure to provide reasonable and necessary maintenance).

(d) Remedy without charge
For purposes of this section and of section 2302(c) of this title, the term “without charge” means that the warrantor may not assess the consumer for any costs the warrantor or his representatives incur in connection with the required remedy of a warranted consumer product. An obligation under subsection (a)(1)(A) to remedy without charge does not necessarily require the warrantor to compensate the consumer for incidental expenses; however, if any incidental expenses are incurred because the remedy is not made within a reasonable time or because the warrantor imposed an unreasonable duty upon the consumer as a condition of securing remedy, then the consumer shall be entitled to recover reasonable incidental expenses which are so incurred in any action against the warrantor.

(e) Incorporation of standards to products designated with full warranty for purposes of judicial actions
If a supplier designates a warranty applicable to a consumer product as a “full (statement of duration)” warranty, then the warranty on such product shall, for purposes of any action under section 2310(d) of this title or under any State law, be deemed to incorporate at least the minimum requirements of this section and rules prescribed under this section.

This is the truth. The 9A1 engine is pretty well developed. You can get tiny power increases through a "tune," i.e. eliminating most of the factory's safety margins on ignition timing. Aftermarket headers and cats don't do much if anything -- the stock engine already has headers and free-flowing cats.

Use that argument and expect something like this in response...
