No problem mattee, I'd be bending their arm to let me go.
Ahhh I see, tornado... Kinda like how my dad felt a spacer with proper inner (rifling we'll call it) properties improved the milage on his suv. unlike the tornado, this throttle spacer had grooves to cause turbulence in the intake to somehow make the air more dense and improve power/mpg/etc.
