Has anyone tried this MBC, what's the forums opinion on this brand?

+3 for Hallman.

Not only is the Hallman proven and available in purple, you can also install -4 AN fittings for SS lines.

I've had the grimmspeed i loved it on my old 2g

I have one on my car works good i like it alot

 

[StarFawkes]

I'll agree with those that say Hallman. I just made a pretty big order through ExtremePSI and if I would have known they were on sale I would have picked one up.

The GrimmSpeed is more comparable too this.

Both are excellent choices and work great. The GrimmSpeed has the adjustment scale and "clicks" with each turn. Other than that its which one you like the looks of.

The Grimmspeed MBC is an awesome item. Description says 4 clicks for every 1 lb of boost, in my experience it was closer to 5, but it was still very accurate once we figured that out. It acted absolutely identical to the Hallman on the dyno as far as holding boost. The boost curves were basically a mirror image. I ended up going with the Grimmspeed because they are local to me; only about 25 minutes from my house.

I used it on my turbo Ford Ranger project and loved it the clicks and have no issues holding boost.

+4 for Hallman

Maybe i just have a bad on or something but my hallman boost controller spikes a good 3-5psi if i floor it. My home made one which cost about 5 bucks to make doesn't have that issue.
