Golf 5 1.9 tdi strange power

[vlavot]

Dear friends, hello, I am a new user here hopefully we will have a nice discussion.
I just bought a golf 5 1.9 tdi and i did a remap, however the first time the golf was on dyno made 120bhp and after the remap it made 155 as you can see from the graph.
The golf was from a previous owner and it has 170k kilometars. So how can this golf 6 speed 1.9 tdi make 120bhp standard. I think it is standard or what would be the mod so that it will make the golf 120bhp.
thank you and if this topic is not in the right section please move it.

Ok so this is the original run before the maping.

Dyno is probably a bit high on it's reading but my one made 109bhp stock and my friends did 115bhp.. they always produce a little more than they are supposed to.

So you are saying that there is a good chance that nothing has been changed in the engine, the person who did the dyno was soo surprised said that the nozzles must have been changed so that it would have 15 bhp more than the normal. Is there a way to find that out,  but than again the dyno person did not know much, they just started, and they had a guy in Italy who did the mod of the maps, the people here are just uploading the maps.
