Hi Robert, I'm glad to assist you. This power programmer does not necessarily improve horsepower especially if there is no additional cold air intake added to the engine. Click the link after this for more product details and information (https://superchips.com/shop/f5-flashpaq-ca). We have a cold air intake available by K&N with part number 57-1509-1. This part is guaranteed to increase horsepower and torque to the engine by 15% to 20%. With the combination of these two parts, the efficiency and horsepower would improve drastically.
