I can feel the difference in towing our 36' camper. Haven't tried the performance setting.

The quality of this product is great. Instruction was very easy to follow. Noticed 3 mpg better on the city. I actually got 4 mpg better on the highway. Definitely notice the quicker response on throttle body and definitely noticed the HP gained. Not exactly sure how many HP at the Wheels. Goo products and recommend to buy.
