Blitz gets my vote. Easy to set up. Has a nice warning and safty feature that lowers duty cycle when boost goes over the set amount. Just a heads up, Mac 35A solenoids(which are used by nearly all boost controller manufactures) work on the blitz units as well so replacement solenoids are easy to come by. Also to the OP. As far as im aware, no boost controllers allow you to just put in a set amount of boost and be done with it. Boost controllers work by duty cycle and are not true closed loops systems.
