The car really feels more alive! This chip was tuned on the dyno to yield as much performance from this engine as possible and still maintain its strength and durability. Jim Conforti tuned the fuel and park maps to take advantage of 91 octane gasoline. By making the engine more efficient with this fuel, gains in horsepower and torque are achieved as well as making the engine run smoother.
