Sure gave my Optima SX a burst of power. I dont know if I’m getting 60 extra hp, but I feel better acceleration and am getting better fuel economy on top of it. I would recommend this chip to any Kia owner wanting to improve their performance.
Got it in reasonable time and simple instructions. Plug and play it was a different car when I let the clutch out in first gear. All gears pulled strong and it got to my cruise speed in almost half the time of before. Can’t wait for the next purchase from Thornton. Thank you guys for a great performance product.
Received my delivery and got it all plugged in, and the average mpg reading on my dash already reade +2 mpg after a 50 mile drive… THANKS!!
I definitely can feel a difference, however I doubt the stage 2 gets a 40hp gain I have a axle back an bov rn, working on getting a stage 2 takeda cold air intake ,resonator and downpipe maybe we will start seeing more of a difference. A lot of kias have a slow response (Kia forte gt and Elantra n lines) when you give it full throttle this will take that slow launch feeling away:)
Wow right off the soon as I plugged in my stage 3 I felt a difference on my 2020 Optima and I have that K&N Filter and a throttlebody spacer and wow the look on other people’s face’s that are behind me they just back right off of my rear bumper love this chip and had the same one before my car was stolen from me back in October 4 and got it back in December 31 and I was so sad when i found out my old chip was missing but I soon after I had my car back I just recently bought a new one and man I forgot how these little guys felt and I’m a very happy camper!
