whats the difference between a a turbo xs high performance manual boost controller, and the turbo xs standard bc?

 

I believe the HP is a bleed as well as a ball and spring.

 

mainly what I want to know is, is it worth getting th hpbc when the standard bc cost less?

 

i've seen the turbo xs mbcs' i own the basic one. the 2nd best turbo xs has 2 adjustment screws one on top and one on the side. one screw is for coarse adjustment and the other is for fine adjustment-saw this one on an eclipse at the dyno that was boosting 18psi and only making 175hp to the wheels cause the car was missing the gasket from the turbo to the charge pipe. the other turbo xs, dual stage just has 2 electronicly controled settings. you adjust each setting and can switch back and forth from in the car.

 

ok thanks a lot man.
