The systems you mentioned work with your factory computer to custom tune the car...you can change timing, add fuel, etc etc.
We like Diablo, and they just released their tuner...you can go with a predator or a Trinity, the Trinity is nice because it holds the tunes as well as can be used as a real time diagnostic tool to monitor A/F, Boost, temps etc.
You will need a custom tune for your Procharger via the CMR Diablo software which most dyno shops have, or we can hook you up with a tuner to help you out via email tunes.
Here is more info on the Diablo...

we tune all of our late model hemi cars ( Stroker, Nitrous, Heads/Cam, and S/C cars with Diablo)
