Yeah, your throttle calculations are a bit off. There is a huge difference in manifold vacuum from idle to 50% but after 50% there isn't much difference to 100% but that depends entirely on your rpm. On the dyno, my car will make 75ftlbs at 2000 rpm at 25% throttle and 100 at 50% and 115 at 100% but 25% drops off to almost no power(35 ft lbs) by 3250 when 100% just finished its first peak to 130 ft lbs.
