$3k for air filter, midpipe and software? They do know this is a Ford and not an <insert German auto brand here>? Is the Hennessey name worth a 200% premium? If so, more power to them, seriously.
Here I thought that some of the more uppity/costlier exclusively LSx tuners/modders were over-charging due to the cache of their names (Lingenfelter, MTI, Mast Motorsports, etc.) for their products and services!
