What do you mean by "real world" answers?

This TSB has some info on P0174 and P0430.

For eliminating the P0430, $4 is as "real world" as it gets.

or try putting mileliminators for $30.

As for the IMRC, if you don't plan to push it above 4K rpm, save yourself a few hundred dollars and don't mess with it. If you want to give it a shot by yourself, try this thread.
