Gfb electronic boost controller G-force 3 $175
 

Installed on my miata but never used. I ended up using the ms2pnp for control boost. Originally I paid $299 so my lose is your gain...ebc for sale. I will ship but buyer is responsible for shipping.

Been using the 2nd version of this for a few years now, its a waay better boost controller than the integrated MS2 stuff, and continue to use it now even after upgrading to MS3.
