I am after a boost controller that will allow me to run minimum boost in order to cruise around town and with touch of a button to run maximum boost in order to let some steam off .
I want a simple device; Which Boost controller would you advise?

When the car is on boost things get lively and loud, by reducing the boost will that decrease the noise, just out of curiousity

Any info on fuel cut? At what bar does the fuel cut intervene? Where is it set etc.?

Would a remap get the most out of the Boost Controller in terms of minimum and maximum boost effect, or does the Boost Controller do that on it's own, or is a remap sufficient without a boost controller?

I think I need more info on boost in order to get my head around this one...

Any suggestions???
