All the Bosch bypass valves are compatible. The 9-3 Viggen and (I think) all new Saabs use the same bypass, and it's far superior the ones equipped on any c900.
As for the FPR, you will see some increase in fuelling with every step up on the FPR. Just remember that a 20% increase in FPR rating does not equal a 20% increase in fuel. Somewhere someone posted the exact relationship (search for posts from Kevin K on the subject). What I can tell you is the, using the stock injectors, the switch from a 2.5b to a 3.0b is about a 10% increase in overall fuelling, so a 2.8b FPR over a 2.5b should be somewhere in the middle - like a 6% or 7% increase.
