On average we see anywhere from 30-90 hp to the wheels and up to 120ft lbs of torque on a dyno. The thing is, these modules aren't made for dyno figures or racing. These are to provide functional low to midrange power in the RPM range you use for daily driving and/or towing situations. Keep in mind that a Dyno measures power at wide open throttle. It can't measure daily driving improvements like rolling into the throttle and holding gears better. These are designed for the 99% of driving situations where your foot is not to the floor.
