also is that a good set up?

Set up sounds pretty good. Vortech says that the S-Trim is good for 20 lbs. of boost.
A car with that set up should at least go low 11's. Probably makes 450-500 hp. (If it is tuned right). Make sure it has an adequate fuel and ignition system. What controls the engine management? (PMS, Chip, etc...)
Good Luck!

My s-trim with a 2.95/6.87 and 3.33/8" both made 18 psi.
