No mention on what other mods are on the test bike- using an aftermarket ECU or a power flow filter cage, or all stock compnents?

was  the bike using pump gas or race fuel during the test? Cahuilla is at 4000 feet elevation, was the test conducted at closer to sea level also? 

all of those things can make a huge performance difference just by themselves, I love FMF stuff, but I would like to see a more in-depth test using stock and aftermarket components to get the most usable power out of this motorcycle.
