The likely reasons are that the engine was not set right after an engine rebuild. Mismatching of pistons, rings and crankshaft weights.
The other reason which is more plausible is that one or more orifices leading to the valve actuating hydraulics is partially blocked. Find out if your friend changed the engine oil the last time he took it for service which could be the reason for him noting a slight improvement.
Last but not the least spark plugs; ignition wires not screwed on properly.
If you do not get a throaty extremely addictive rasp when at about 4000 to 4300rpm especially in third gear some setting is not proper. Engine noise could be there but I have not seen a single GTX that has engine vibrations at any rpm other than within normal expectations.

Quiet a similar thing is happening with my palio adventure 1.6 sports. I just got it two months back, and its engine given me a sound of rattling or similar to like a diesel engine, although this noise as much as of a diesel engine, but significantly more then a petrol engine.
I reported the same to service center, and they put some tool to some electronics port in engine and said that everything is fine. He just said that he has cleaned and adjusted the spark plug gaps, and this will do it.
But still the noise is there with same intensity. I am again going to take this to service center, but the thing is again he will put that tool and said that everything is fine.
Can you suggest how to know the exact cause, are there any specific tests for that, or is above a user understanding and only service center guys can do that?
