I used these items up to 1/17/17 upon replacing my FIC/6 with a MSPNP Pro.

Turbosmart MBC. Works great. Minimal boost overshoot
for a MBC. These are about $85 new plus shipping. How about $55 shipped?

Go Fast Bits Turbo Fuse
These are great if you are running a piggyback system without electronic overboost protection.
It was nice to have peace of mind while tuning the upper parts of my map myself.
Very easy to set up, very reliable and a soft boost limit that is adjustable from 10 psi to
higher than any Miata has a right mind to go.
These are $165. How about $110 shipped?

 

TurboSmart MBC sold to 18psi!
thanks.
GFB TurboFuse still available.
