I do really hope Cruzin is just joking about the non-NeedsWings intakes being slower...
Could anyone be that product namebrand conned?
Anyway have you tried to install the stocker to see if it actually feels stronger? A lot of times when we are modifying we expect alot more than we get and the mind does all kinds of things.
Generally even the sound change makes one think we is running faster than before.
It would cost you nothing but less than a half hours time to switch them back and forth.
Good luck...
