Very cool. Also great to see the piece by piece numbers from each mod. Notably, that the stillen CAI gained only 6.3 whp and that he gained 42 whp with intake, cat back, and ecu tune. It would therefore be reasonable to gather than with a HFC or Test pipe it would be around an even 50 whp over stock (even with hps hoses and KN filters instead of a CAI), which for a 6 cylinder N/A car is rather impressive IMO.

Might have to check out this shop. They're 90 mins from me.
