I checked out Powerchip’s site. Powerchip claims a 9% increase in net horsepower at the crankshaft (21 hp gain). Mbtuner’s dyno output shows a 5% increase in horsepower at the rear wheels (9 hp gain). That is an interesting discrepancy. Nevertheless, I am interested in their product.

I have a few questions about the impact of Powerchip’s product on the car manufacturer’s warranty.

Powerchip claims that the car manufacturer’s warranty is not affected by their chip flash. To support this, they quote a couple of lines from a position statement by the Specialty Equipment Market Association (this statement is SEMA’s opinion and not a legal document).

Has anyone on this forum ever had a warranty denied due to an after market chip flash? Has anyone ever been in a dispute with a dealer over a warranty due to an after market chip flash? Has anyone actually received anything in writing, in advance, from a dealer regarding after market chip flashes and the impact on the car’s warranty?
