First of all I know my results are not the most accurate in the world so take them for what they are worth. I never did a baseline run with my truck but did a pull with intake (JWT popcharger and some homemade parts and a Gibson cat-back). I put down 164 to the wheels and produced 232 ft/lbs of torque.

Based on the numbers I have seen on stock SC trucks (K&N's testing of the FIPK II) it looks like I gained about 12-14 horsepower. I can;t recall the torque gain off the top of my head...

Now I know that there are so many variables that could affect the numbers: temp, altitude, etc... So I consider mine a general idea of the gains.
