Can I trust "desk top dyno 2000"

[NotchJohnson]

After reading this thread I just downloaded deskot dyno 2000 off kazaa. I was playing around with it a little and I entered in my buddies old 306 combo. I dont know if someone added it in later or not but it when I downloaded it, i also got a bunch of cam files and flow files. My friend had out of the box tfs tw heads, a vic jr, a 650 holley, 10.1:1 comp, and the comp xe282 can. I put all that stuff in and n/a it throws out over 450hp and about 400 ft/lbs torque. I know for a fact he got 340 to the wheels on the dyno with the car. Are there other things involved with the program. I noticed it doesnt ask about what kind of intake, only if its single or dual plane.
