Default Power Question - S/C'd

Hey guys quick question...

ive got a 04 Roush 440A, completely stock aside from exhaust and COPs and also a CAI, as well as 4.10's

My exhaust is LT's, with O/R H Pipe, and flowmasters.

When I got the car tuned, I put down 348rwhp, and 326 TQ. Do these numbers seem a little low to anyone? I felt like I should have more torque. I'm running the stock pulley, pushing 8 lbs of boost.

Maybe im just crazy and paranoid something is wrong. Any suggestions?

The thing is, all dynos read differently. Some are conservative, some are optimistic. You can trick the dyno to print out whatever hp number you want to see. Dynos are best used as a tuning tool, not a number generator for bragging rights.

I put a saleen supercharger in mine and I got 384 hp and 358 tq... I think my torque is too low too but it's still fun to drive. At the end of the day it only matters if you win, not your numbers.

Define stock motor, a stovk 2v on 8psi isnt making 420rwhp especially througj an auto. What compression is this "stock" forged 2v.

It definatly has to be pushing more than 8psi especially with an auto to make those numbers
