Which is best boost controller

[hybrid dreams]

never thought of a purely mechanical boost controller, so you have some info of where to aquire them? How easy are they to fit?

Used to use these all the time, if you are just wanting a few more pounds of boost and don't need the ease of adjustment of an electronic device I would thoroughly recommend them and for around

I used a profex B spec II for about a year with no problems. Straight foward, easy to set up and nice and small. Boost now however goes through the power FC so i can select 4 set levels.

am just thinking of something temporary until I fit a new turbo and get a new boost controller. So might just by a mechanical one for the time being.

Depends what you want to do with it. Apexi AVCR is still very good and has some features that you don't find anywhere else. The Turbosmart Eboost is very capable indeed, but ideally benefits from the addition of a few switches and careful setup to get the most out of it. Greddy profec B is easy to setup but not great at making a turbo hold boost to the redline.

It's a shame there isn't a "perfect" boost controller with all the features I want. The best boost control I've come across is certain models of the standard Subaru ECU, some have over 20 maps for boost control!
