Anyone remember seeing a thread about being able to load the 05 calibration onto an 04. I've been searching for the past hour. Wondering if it was maybe on another forum. Anyway, i know it' possible, I'm loaded it onto my 04 today, and the car feels a whole lot smoother, unsure of any power gains. Anyway everything runs fine except the speedo only operates between 0 and 20 and the odometer seems to have slowed down as well, not sure why this would happen consideringthe wheels, tires, gearing are the same between 04 and 05. Any thoughts?
