Are you planning any sales for the LAP3 Uncle Chip or plugs? Or possibly special bundle pricing on the chip and recommended plugs?

And it seems a few 2.0T Stinger owners in this thread did the LAP3 uncle chip install without upgrading plugs in this thread.

Here is the email thread from March: On Dec 15, 2017, at 11:20 AM, K5 Optima Store <sales@k5optimastore.com> wrote: Hi Scott, The singer does not require upgraded spark plugs as the spark plugs from the factory are built strong enough to handle the tune. Only other models of Kia and Hyundai...

I emailed David at the store in march and he said the 2.0T factory Stinger plugs were fine with no need to upgrade. I'm checking in now to see if that's changed. Did it?

Who has kept stock plugs running 92 octane with chip on 91 setting vs going with the plugs listed on the K5 store page? (http://www.k5optimastore.com/collections/new-products/products/hks-m45xl-spark-plugs)

Surprised the overall ride is stiffer given the Eibachs are progressive springs. I had them on a G35 and the overall ride quality was better until you really pressed the car (and the springs) to the stiffer rate.

This almost sounds backwards, as higher altitude stations should be selling the higher value RON.

The 2.0T (I have a Premium model) allows for manual lockout via the shifter, which is how I drive it all the time (just like my 2012 Optima SX). Driving in this mode also disables the auto stop go feature.

Let's hope they make these for the 2.0T AWD model also...

I like my 18" wheels that came with my Premium AWD 2.0T model. Interesting find on the 19" factory ones for cost. I think it would be more interesting if we found the weights of all the wheels that come from the Kia factory...

Tried calling my local Kia service department for factory alignment specs and tolerance ranges for GT and 2.0T (both RWD and AWD for both models). They didn't have them. Does anyone have these or can you get them from Kia North America? I might consider going with a little more aggressive...

How is that racing Optima holding traction? From tires alone? I could get tire spin and fish-nosing with decent tires at various times and conditions without any mods. Many other Optima owners have mentioned this also. This is one of the major reasons why I traded in for the AWD 2.0T...

Is the Uncle Chip actually increasing boost? Interesting if it is. A fouled plug could be bad / incorrectly labeled / lower octane than advertised gas. How easy is it to test the rating of gas?

oh, my other fun car...

Looks interesting. I have a 2012 Optima SX and hope to be trading it in very soon for a AWD 2.0L Stinger Premium.
