I barely ever get replies, its sad.
Also worth noting is what octane. Its easy to make big numbers by using race gas, it also tends to mask bad tuning by adding extra detonation protection. Looking at the PSI and Octane will give you an idea about how relevant the tune is for daily driving. Though this certainly does not tell the whole story.

More good advice is checking to see if the HP and Torque cross at 5250 rpm as this will let you know whether or not the numbers have been tampered with via a correction factor. The formula after all is HP = TORQUE X RPM 5252.
