Review on 💪 Increase Fuel Mileage and Horsepower with Innovative Performance Chip for Mazda 3 2.0L, 2.3L, and 2.5L Engines by Bill Russett

First I would like to say that the assembly instructions are very poorly written. It's not clear which wires you're connecting the device to, and since your year, make, and model are required to order the correct device for your car, you might think this information might be included. The only thing this product did was cost me money. in repair. It attaches to the MAF sensor wires and as a result I had to replace both the sensor and the wiring harness. I would not recommend this product at all.
