Marco, centrifugal doesn't build as much boost until the highest rpm's, so you're gonna see the boost drop off between gears. It should get back up to full boost near your next shift. That's another difference between the Radix and the Procharger. Also, remember that your cam is HUGE when compared to most boost cams.

A converter that is spec'd out for your exact setup will yield better results at the track. You know now better what you are looking for, since you've had the procharger at the track. Make sure you talk to them about what kind of shift extensions you are looking for. You could talk to Dave at Yank, or Chris at Circle-D, both guys are very helpful.
