Default Need a good MBC

I'm looking for recommendations for a good MBC to work with my Tial F38 WG and 7psi spring. I'm peaking at 6psi on the Tial alone and want the ability to raise boost to 8-10psi.

FWIW, my WG vacuum source is tapped off the comp housing and I'd like to keep it there even though it opens the WG earlier.

turboxs is a descent one....and you can still leave your vac line where it is.....youll just have to tap into the one from your compressor to wastegate to make a line going to the boost controller....then run another line from the top of your wastegate to the boost controller......wala(sp)

Thanks guys. I looked at TurboXS, Turbosmart, Hallman, Turbo Logic, Joe P and numerous others tonight. The best one I found (IMO) was the $120 Hallman Pro RX with anodized billet body, ceramic BB and 2 interchangeable springs. The best value I found was the $20 US made NSX MBC on Ebay. I went with function over form again.

In the worst case, I might have to spend 15 minutes re-working the brass bodied NSX MBC so it works as smoothly as the Hallman but given the fact that I don't make $400 an hour, I'll still be ahead.

Thanks for the interesting links. For me, the extra $10 I paid is well worth it to save the 2 hours I would have spent getting parts and making one. It only takes a minute to walk to my mailbox. ;)

The Hallman is nice but this does the exact same thing only with a brass body instead of billet AL. I don't like the bleeder style either.
