Traditionally this mod on many platforms pick up torque downlow and HP in the 3 to 10 hp range in the lower RPM. Also if you run the car longer it won't slow down. We had a customer dyno his car with these and he did 4 back to back dyno pulls with NO drop in power. Unfortunately he had no before dynos.
