The Profec is tried and true, though I have a TruBoost and it works just fine (I like the gauge style better than another damn little box!). Retuning largely depends on the existing tune. If you're non-seq already and they tuned it safe up to say 15psi then you have some playing room. If it's pretty on the edge at your current levels then upping it would need some rework. You'd probably need to talk to whoever tuned it.

The chief advantage to the TruBoost is the gauge layout. It is a "dumb" boost controller that cannot adjust the consistency of the boost (open loop only). That is why there are no gain settings, only a basic duty cycle and wastegate spring setting.
If you have a Haltech you could control boost with that. But the fact that you are asking these questions indicates to me that you should look at the Greddy Profec Type S (which is like the old Profec B they don't sell anymore). The type S is a very simple boost controller to configure, simpler than either the Profec B Spec II or the AEM Tru Boost.

There are some advantages to that price though. Closed loop offers faster spooling, and more precise control especially under varying conditions where a set duty cycle can't compensate. If you can, look for a used Profec first before deciding.
