Are the hp/torque gains for the 5.9, with Gibson headers, that they have posted on their site legit?

What are the numbers. Im too lazy to look'em up

when i put the gibson headers on my 02 r/t i could notice nice throttle response and an increase in low end, i don't think i got the gains the site claims tho.
