These percentages seem a bit high compared to what I have seen. I usually see/hear about a 1-3mpg and 10-30% HP. I understand the point you are trying to make but "doubling of fuel economy and about an 80% jump in horsepower" is far from accurate, especially considering the downsides of a delete on every outside of the vehicle
