Performance mods on this car originally started out with an OTS (Off The Shelf) tune from SFR (Seoulful Racing) where it dyno’d 258whp with a base dyno of 236whp netting a gain of 49 whp over stock. Later, I had the opportunity from Turbokits.com to take a step forward for the US KDM market in the building of a big turbo kit for the 2011-2014 Sonata 2.0t and 2011-2015 Optima 2.0t. This car became the R&D car for the Turbokits.com turbo upgrade kit for the Sonata and Optima 2.0t platforms. With Level 10 transmissions being roughly 100 miles away from Turbokits it only made sense for me to wait and get my transmission upgraded with the Level 10 bulletproof transmission upgrade before making the trip from El Paso, TX to pick up my car. This car put down 411whp/401tq on the stock engine. The engine was upgraded in September 2019 and now has a Precision 5558 gen2 which is a much better turbo than the previous TK5454 that came as the base turbo on the Turbokits.com setup. I now have a 400+ whp/tq daily driver that is a sleeper in its truest form and a very fun car to drive. These upgrades completely transformed this car. Update 20200505 After building the engine last fall I scheduled the car to get tuned and due to the current situation with the covid19 virus and the tuner having to fly from Korea. I decided to go ahead and turn up the boost on my current tune that was designed for the stock engine and see what the car is putting down. I hit the dyno at a peak of 32 psi and layed down an amazing 512whp and 439tq.
