Hallman MBC Pro / Pro Rx?

[Twinturbo2800]

The only difference i can tell between the two are that the Pro has a metal ball, And the Pro RX has a ceramic ball and 2 different springs.

If i just buy the regular hallman pro with metal ball can i still get 16psi from it?
Is thier really any difference with turbolag between the ceramic and metal balls ?

Thanks, josh.

If only boosting 16 psi the regular is fine. The ceramic is for higher boost, i.e. 30+ psi. As for the lag, all boost controller operate the same. Turbo lag is all base upon what kind of turbo you have, i.e. journal bearing, dual ball bearing, etc... and what type of internal or external wastegates.
