Not my words but from post #5 in the thread at the bottom
"Bosch OEM... I'll put it this way... this week I had a client without funds to purchase genuine MB injectors, so they opted for Bosch OEMs at lesser cost to them. The initial order of five injectors yielded two that were within specification. One of them exhibited no chatter and simply streamed its fuel. This is unacceptable, but is and has been the norm for a number of years. I would not install any Bosch OEM injector without testing it first. They can not be trusted without testing, in my opinion. These are typically rebuilt in third world countries, hence the decreased cost and poor quality control.
Local rebuilder? If you have a local outfit that is skilled with these injectors and is using a quality nozzle, there should be no problem withe them. However, you want to know the pop pressures and to witness the spray patterns first hand. I would not trust someone's word on the matter. Fact is, it takes some time to dial in an injector for optimal performance. It is quite easy to throw one together and to get mediocre performance."

Back to me. I believe Rebuilt Injectors that are grabbed randomly from a parts bin will most likely not be balanced. Due to the allowable range of pressure of 1958-2074 psi that they can be rebuilt to.
As that guy said in post #5 of that other thread a local shop will try to balance them much closere that the max allowable 5 bar (72.5 psi).
