I could help clarify some of the misconceptions.
As Anthony said awhile, while back Livernois received a customer who had our first generation intake system (smaller filter, different filter design, no heat shielding) which they used to test against their intake on their dyno and then reported back that our intake lost horsepower.
From another unbiased, third-party testing done by a member of this forum who is located in a different state than us and used a dyno shop that we are disconnected from, we had seen gains going from an AirRaid/Windstorm to an MDesign first generation intake in horsepower and torque. These are our unbiased facts.
http://www.ecoboostperformanceforum.com/index.php/topic,4034.0.htmlBoth of the testing above were done with our first generation intake systems, we have also had our first generation intake system tested at the track which fell within .01 second of the Windstorm and the OEM intake systems in the 1/4 mile.
For quite some time we have been receiving Livernois customers who have been told that our intake is inferior to the Windstorm/AirRaid though it is never mentioned that they are comparing to our first generation, discontinued model and we are on our fourth generation. It is also not mentioned that the Windstorm/AirRaid only won over the MDesign intake system on the Livernois dyno, in their own shop, while we have unbiased third-party data. This is why we only post data that we receive from clients who perform these dyno testing at unbiased and disconnected interest shops across the nation.
