First off, yes running two separate turbos is an entirely different story. Second, you can't fairly compare an IDI to an 06 Cummins on power (or almost anything else). The computer controls and the piezo (spelling?) injectors make the two SOOOO far apart that the biggest similarity is that they both burn the fuel out of the same pump. Third, although 50 PSI on an IDI is extremely unwise, I don't see why it would be that way on a PSD, especially one that's newer than a 7.3L. Now my won't be accurate, but only in the ball park. The reason why a Cummins, Duramax, or a PSD can run so much more boost PSI than an IDI can, is because of the differences in compression ratios. The IDI runs about 22:1 while the others run about 17-18:1. I'm sure that there's other reasons, besides this, but this is probably the biggest one.
