Another benefit from the UpRev offering is the Cipher software. Unbelievable software; you can log practically every sensor on the canbus** (not "literally" every sensor).

Also, just from observing the two product offerings on the g35/350z platform, I would suggest that over time/into the future, the Osiris product will offer more tuning parameters. I don't know if Osiris will ever allow for tuning the VVEL system, but if either company ever offers such functionality, it will likely be UpRev and not Cobb.
