So im getting that the turbosmart one is the better choice. And ill have to get a bosst gauge too. And the power depends on how much boost you set it too and im guessing the max boost is like 20psi?

20psi is about the limit i think. i dont recommend that much without a fuel pump either. trust me i'm doing it ! when it gets real cold outside my car still stumbles and fuel cuts at that level. on a stock fuel system i dont recommend holding more than 18psi... spikes a littler higher are ok. i do it, cuz i'm kinda care free. i figure it it breaks......forged internals here i come !!
i do have a fuel pump paid for and comming too !

spring/ball style MBCs have different material in the ball that allow for more specific and accurate boost control. Some are delrin/plastic, some are ceramic some are metal. The different type of ball accounts for varying prices on simple ball and springs MBCs.

Also, most electronic boost controllers use a solenoid style interruption response boost control, which is considered more precise and accurate for boost control than most 'bleed style' manual boost controllers.

A basic Hallman MBC can be had for around $60. Or you can spend $600 on Apexi AVC-R which is an electronic boost controller has an integrated RPM sensor and can vary boost according to engine speed, gear, and throttle position.
