I've never had to use one, although my father in-law has one which 
should work. I suspect timing is not your problem here though.

suggest to me the pump and/or injectors are the problem. My Jetta TD 
idles and drives much quieter than the original non-Turbo engine. The 
fact that the TD injectors are noisier though, suggests to me that 
maybe your old ones are releasing pressure too soon (or the pump is 
not functioning properly with them), resulting in a sort of "staged" 
ignition, which would be quieter, much like the system used in the 
TDI.

Just a few thoughts; those two statements stood out as being odd to 
me...
