Anyone have tested boomba TB and IM spacers?

Hi there I got a 2015 EBM with Map intake and COBB AP Stg1.

I was looking at the boomba racing spacers does anybody have tested them and confirmed that they indeed do something. I have never ever believed in Tb or Im spacers FI cars.

No need to believe in them now. The TB spacers can be nice for a meth nozzle or nitrous nozzle.
