Dyno operators can easily manipulate engine loading on runs to prove what they want you to see.
There is no way you'll see a 30-40bhp gain on a normally aspirated, 3 litre production motor by just a remap, unless the original map was somehow corrupt and your car's performance was well under par before you started.
Perhaps he/she fitted throttle bodies, cams, ported the head and re-mapped the lot while you weren't looking?
