Thought it would give better gas mileage, but really haven't seen it. Easy to follow directions and updates installed. It may growl a little more, but I also installed a k&n air filter at the same time and it was supposed to be a boost and still haven't seen any boost with either! So maybe if your foot is always in the gas it may save some, but the Tundra 6 speed is a shift monster and I did notice shifting differences but no change in my.
Works as advertised!
I finally pulled the trigger & bought this afe booster for my 335i f30... there's a refund option so I figured why not... try it & return it... i tried it & im never returning it. This should be a 1st mod for most cars. Makes it more drivable, more fun, maybe the way the way the throttle should have been made. The price is high but it is worth it. No added power but it make u feel all the available power more instantaneous. Buy it cause u wont return it.
