Tornado Air Management vs. Vararam Velocity Stack

[morepower]

Has anyone out there purchased the Tornado Air Management system ($70) or the VaraRam velocity stack ($50)? I have seen both of these products on auto shows on speed channel and Spike and just wondered if anyone has used them....and if they actually work. They both promise increased fuel milage and increased power by putting more air to the intake. I have a K&N filter in the factory airbox...and was looking for additional help. I'd like to see some milage and power increase on my 5.3L Yukon without spending a fortune.

I have the Vararam in my 5.3 and felt it right away. I was skeptical at first but now I am glad I purchased it.

The tornado is a waste of money.

Tornado or SpiralMax, same idea just different manufacturers for both in the newer GMs. I have 1 each in my '00 Silverado and '03 Suburban. Can feal the difference in both trucks. Also slightly better fuel mileage.

Tried the Tornado in a '03 F-150 and no difference at all.
