Completely different truck now, my 08 Ranger feels like a race car, it shifts much faster. I cant believe the change this little blue devil toy makes, my fuel dropped only because i have a lead foot. I'm only using default performance use. I will try the economy setting and let off the gas once the novelty of using this wares off.
