Tornado: legit or marketing gig?

Sup peepoz, I'm sure you've seen the Tornado "Air management system" on TV. It looks persuasive. Has anyone had experience or know anyone who have had experiences with it? Does it do what it claims or is it just another one of those marketing gigs? Furthermore, are there any upgrades that improves fuel econ. as well as performance? Thnx in adv.
