Can new injectors really increase noticible power and fuel mileage ? Can they reduce minimal smoke down to zero ?

I know that many of you have changed your injectors so share your results with me.

Thanks

First off, leave well enough alone, unless you know you have one or two injectors that are causing an engine to lope at idle and might be attributing to poor fuel economy or something.
rebuilt matched injectors are the way to go. Search for the subject India and injectors and you'l see why

I changed the injectors on my 240D not too long ago. I had them balanced by TOMJ (forum member) and the car did get more MPG but it wasn't faster. He also matched the injectors up with german nozzles and balanced them. He did a great job but I just changed the injectors for the heck of it.... they were not bad. Mileage went up by 3mpg

More mpg is good.

I would pull the injectors and check them. If the tip shows serious visible wear I would put in rebuilds. My one mercedes maint book from mercedes source talks about how to visually inspect them. It is probably best to have a source for injectors near by so if you pull them and they need replaced you can go get them and not have to put in new crush washers to put the injectors back in.

New injectors improve the spray pattern causing cleaner burning meaning more power, better fuel economy and less carbon crap.

Hrm... I may have to get a few sets next time I'm out in the yards.

What special tool do I require?

It always surprises me how reluctant people seem to be to simply take the injectors to a shop for proper testing. I own 3 diesel vehicles and I have thought about either buying or making an injector tester but I decided its not worth my time. I don't have the time, effort and I don't mess with injectors enough to warrant the investment. If you have doubts about injector performance take them to a reputable shop and have them take a look. Its very cheap, easy to do, and then you know they are working correctly. RT
