This add on was a good investment so far.... It seems that I have noticed a 1-2 mpg difference. I have noticed a big difference in throttle response and low end torque. The only thing that i don't like is when you have the throttle 1/8 open it whistles. Hopefully they can engineer the next years model not to whistle. Very pleased and good bang for ur Buck!
