Review on π Innovative Performance Chip/Power Programmer for Hyundai Genesis 2.0L, 3.8L, 4.6L and 5.0L β Boost Fuel Mileage, Save Gas & Gain MPG, Enhance Horsepower & Torque! by Joe Nieves
I had this product on my 2015 Genises sedan.
I have been using this product on my 2015 Genises sedan for two full weeks now and have not noticed any improvement in fuel economy or performance. I'm starting to think I paid for the blank black box attached to my card sensor!
