Manual boost controller or Electronic/ECU boost control? Which one?

I've used both, previously had a Hallman and I'm now running a Grimmspeed 3-port on stock ECU. ECU controlled boost has many advantages that I've seen so far: Gear dependent boost control, boost error correction (great for temp changes), dual boost maps, rock solid boost, quicker spool, and holds better up top, decrease boost on knock, etc. The cost is about the same as a good MBC and setting up the base maps isn't too difficult.

Hallman MBC over here and love it, had the GReddy Profec B and like stated before its a good unit hard to dial in for sure just wanted something simple again, so took the GReddy Unit out put the Hallman back in GReddy unit's for sale any takers PM me 
, but if I had to do it all over again from the start it would be in this order
MBC if budget is tight
ECU controlled for the best bang for your buck and being the most efficient IMO..
EBC if you want to have a hi/lo setting or be able to adjust for cold weather/hot weather, and having it as a secondary boost gauge, limiter settings, and visual and audible warnings were a plus too

but if i had the money to blow on a EBC I would buy a Blitz SBC i-Color Boost Controller. It looks sick and has lots of functions and it has a easy to read color LCD screen. It comes in silver or black.

does anyone have graph showing the spoolup differences between an EBC and MBC? I have to think with all the logging going on SOMEONE took the time to log the difference between the two.
I have been running an MBC for as long as I've owned boosted cars. Now that I'm on V7 I'm moving over to an EBC for various reasons. I fully intend to log the spoolup difference recorded by my MAP sensor between my Hallman and whichever EBC (grimmspeed, Perrin) I choose.

Id go with ecu boost control for a couple of reasons. Im not sure if you run dual maps on your car, but if you do using the ecu to control your boost levels between different maps is much easier than counting turns on a mbc. Another thing is if youre into carshows or showing off your engine bay at all a mbc can be a big liability. All it takes is one punk to walk by and turn that knob a couple times and bye bye motor. The downside is that they are not user friendly, if youre not a tuner you cant really play with your boost levels on your own, which Ive found is a good thing for some people.

you can also use the I/C sprayer button if you have one or the patch that uses the throttle pedal to change it. A friend of mine runs his that way

I like my Grimmspeed 3port, I can hold 30psi no problem on my Red and my Black till 8000 rpm. Also I can change between low and high boost at will, if I have my laptop with me, which I usually do. You can also correct for changes in temperature which is good. Not to mention that you can play with your boost in 1st gear for a perfect 2-step which is crucial if you want to take a GTR off the line

I used a small toggle switch with a LED hooked in. switch in the off position is low boost (91 octane) and switch on LED lit is the high (e85)
