Review on Enhance Performance Chip/Power Programmer for Kia Optima & K5 1.6L, 2.0L, 2.4L, 2.5L, and 2.7L - Boost Fuel Efficiency, Save Gas & Maximize MPG, Amplify Horsepower & Torque! by Miro Dadee

The 1st support was top, there was a question that was answered promptly and accurately. The second performance was amazing! My car (13 Kia Optima SXL 2.0 Turbo) has performed well before and I wanted to walk as my foot is a bit too heavy. Not sure of the mileage yet as I'm still on my 1st tank of gas since installation. But honestly, I don't care about the mileage because I get too much enjoyment out of the power increase. You have a great product for the price and I have recommended it to many people, some of whom have already ordered it. Keep it up! Thanks very much!
