Review by Chris S. on 13 May 2020 review stating Chip works great. Make sure
Chip works great. Make sure to gap your EXPENSIVE spark plugs by an expert or the installation can hurt your emgine. My plugs worked for about 24 hours and then foulrd. Installer issue. I bought the highest end tech money could buy, but if your shop can't install it...you either do it yourself or by a shop you trust that does this kind of thing daily. The chip works AWESOME. My turbo spun up far more responsive and it spun in 1st, 2nd, and hooked up my Michelin MXV4's in 3rd for a huge surge forward. This kit is the real deal. It is EASY to put in....if you know how to gap Iridium tipped plugs at .028 w/o screwing it up like my "installer" did. Not happy with installer. Very happy with quality and ease of connection with this system.

Review by Matthew S. on 2 Jun 2019 review stating Huge performance difference and to
Huge performance difference and to my surprise a big change in fuel consumption. Better performance and better gas mileage all at the same time. Very pricey but worth it. Always have to give credit to David for the excellent customer service.

Q: How does this not void warranty?
K5 Optima Store
05/20/15
A: Matthew,
This does not void the warranty for a few reasons. First being that nothing you install on any vehicle automatically voids the manufacturers warranty. Many consumers believe that to be the case, however it just does not work that way.
In order for a manufacturer to void the vehicle warranty, there has to be proof that the consumer installed something that was the direct result of whatever component they are trying to void the warranty on. Meaning, the part you're installing would have to have damaged or destroyed another component on the vehicle, and the dealer would have to prove that for them to void the warranty.
Secondly, this tune is completely undetectable by the dealer altogether. It is a piggyback setup that does not connect to the OBD2 port and cannot be seen by the GDI scan tool the dealerships use.
(Please read up on the Magnuson Moss Act for more information)

Q: It sounds as if this needs to remain plugged in (rather than plugging in, downloading data, and unplugging)--is that correct?
K5 Optima Store
05/21/15
A: Justin,
Yes this is correct. As long as it is plugged in, it remains working. Once unplugged, all signs it was ever installed are gone.

Q: Why does the ordering options ask what octane settings you want if it comes preloaded with 3 octane ratings?
K5 Optima Store
06/10/15
A: Ed,
This is because we take the time to set it up for you prior to shipping it out. Not everyone has the tools to take apart the chip and change the settings. Most owners use the same octane type when getting gasoline, so we set it up for you so you're all ready to go once you receive it.
Thanks,

Q: Do you need to install a catch oil can for this tune and if so which one would you recommend?
K5 Optima Store
06/10/15
A: Hi David,
Yes we definitely recommend installing a catch can with the tune, as well as better spark plugs. We carry the plugs on our site as well as a few catch cans as well, but will be adding some catch cans to the site this week as we just got a brand new line of catch cans in stock here in several color options.
Thanks,
