I used this on my 2011 Hyundai Sonata 2.0T and had a blast! Instant power, improved throttle response and more boost. Definitely best mod/upgrade for your car. I used this for about a week and had no problems whatsoever. I just decided to send my ecu to seoulful racing for a canned tune so I have no use for this. Asking $375. Price is negotiable and doesn’t include shipping.
