You can program the EBC to keep the solenoid shut until it sees a certain amount of boost, THEN open, thus spooling the turbo up a little quicker. An MBC, on the other hand, is open all the time. If I had the gain setting turned up, it spooled up fast, but it had a tendency to overshoot my desired boost level (spike) and then settle down.

It's not SUPER noticeable... but it's noticeable. I don't know that I'd consider it worth the price difference based on that alone.

What I liked about the EBC over the MBC was that I could have it set, and then with the touch of a button, turn it off, or turn it up (with the 2nd boost setting).

I'd still have it had I not killed it (a zip tie failed, let the solenoid wires drop, they hit the manifold, melted, and shorted the driver circuit out) but I put an MBC in its place (didn't feel like dropping another couple hundred bucks) and haven't really felt like I lost anything. In fact I prefer the slightly slower but smoother spool up of the MBC.

I mounted mine on off the firewall sort of. I had a thread sticking out near where the cruise control unit sits i let it hang there and used a piece of rubber and treaded it as a nut and holds it in place. (looks like where the factory zip tie would go on but theres no cables running there.
