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

I ordered this a while ago, barely got to the review. As other people have said, ask why? Well, the simple fact is that COBB does not have access ports for Mazda 3 NA vehicles. Just Speed3, that's a whole different demon (alternative reference) lol but I'd recommend it if you have the money. MPG increased by 7-8 in the city and 12 on the highway. HP was dynamized with an increase of 42 hp. Don't remind me tk.
