Anyone had experience with having injectors EDM or honed?

Keep seeing this in Diesel Mags and was curious about it.

They wont do any good unless they make the plungers bigger...

So just get bigger injectors and be done with it?

Thats probably your cheapest route to getting fresh injectors.

EDM is where they electrically enlarge the nozzle (not sure of the specifics). EH is where they force a fine abrasive paste through the holes to enlarge them.

From my experience EDM make more power with less smoke than a similar flowing EH nozzle. I started out with .0085" EH nozzles on my 530's and was running SLOWER than i was with hybrid inejctors (.010 EDM), stock hpop and a smaller turbo. I picked up over 50rwhp just by switching to .012 EDMd nozzles from the .0085 EH. Yes i know the EDM are bigger, but they flow very similar to the .0085 EHd nozzles. Ive been told EDM tend to have a rougher hole finish and i think this helps the fuel atomize better resulting in more power and less smoke
