I was reading on another forum about adjusting the VE pump back to OE specs, including timing and "internal pump pressure", which sets/affects dynamic injection timing.

I ordered some injector cores to clean/rebuild, and when they're ready to go in, I also will check/adjust internal pressure and static timing.

I plan to pop test the injectors to 130 bar, the OE setting for N/A injectors. Turbo injectors are 155 bar, but the extra fuel pressure isn't necessary for fuel atomization, and takes a good bit more energy, which means more fuel burnt.
