does it make a noticeable difference in power

It helped on power but instant notice in throttle response and mialage went up one added while a 3" lift and 285/65/18's "heavier rockstar kmc 18's" were added so on lighter wheels and stock tires probally make a bigger difference.... MUST SELL 250 SHIPPED!!!!
