Joe...

It's not just the restrictor itself...it's the clean implementation of it along with filtration/HFM/etc. into our intake tract.

Our space is severely limited with twists and turns from the OE intake position to the TB.

If we didn't need filtration it would be SIMPLE to implement the SIR...but...we do...so...it ain't.

Pleasse explain what majic bullet you think Bimmerworld is gonna come up with here? I am really curious what you think they are gonna find. Have any of you guys read the information on how an SIR works? Don't wait get the unit and install it. best case is somebody may come up with a 1 or 2HP gain BIG DEAL get it in the car and start testing the main thing your gonna need is seat time to work out how the lower peak power is gonna effect you. NOTHING Bimmerworld or anyone else can do will make up for seat time.
