Review on Innovative Performance Power Programmer Infiniti Replacement Parts : Engines & Engine Parts by Tristan Graham

This product is phenomenal. The EPA fuel rating for my 2017 Infinity QX50 of 3.7 puts it at 17 city and 24 highway. The best I've ever had was 23 mpg. I drove from Florence Arizona to Albuquerque and got 28.8, gasped at Costco and came back 3 days later and got 30.8. My computer said 33 but I checked both directions manually. do you think i'm happy? I EVER, it worked way better than advertised. I kept 65 on the track trying to slow down. I'm still impressed with the performance this product has given me, if I hadn't tested it myself I wouldn't have believed it. Thanks for the super product. Don C
