PROFEC B-SPEC2 , who has one?
I have one. It holds boost pretty well, although it took forever to get set up correctly. I love having the 2 different settings. Actually, it's like having three settings because if you turn it off you run the wastegate spring pressure (~11psi). Once it is set up properly, it works very well.

Its the same for me, i have one on mine right now, i love it, holds boost great, better then my previous mbc (turbosmart) took forever to tune, but once i got how to do it, it was alot easier to handle
