Excellent point; I have the MS stage II intake, and at high speeds, there feels like there is more power and hits redline quicker, however the combination of low RPM and low speeds (below 30 mph), there definitely feels like there is a pressure drop, vacuum-effect that feels like it's reducing low-end torque when throttled. It's a tradeoff I'm personally willing to accept, but would be nice to see intake pressure, AF ratios, as well as dyno measurements provided by the manufacturer/key resellers to make sure everyone knows what they're getting into when purchasing and would result in the highest customer satisfaction.
