also when the gtech supposedly calculates hp, it doesnt take into account fwd, rwd, awd, or gear ratios, tire and wheel sizes, or pretty much anything but time and weight. a car with 400 hp and a car with 200 hp can run the same time, depending on these variables. one said my car has 240 hp, i know for a fact my car has a lot less than that, as it came with 160 stock and only has an intake and exhaust, its prob really got about 170hp.
