Thank you Mates!

I have rebuilt my injectors using Monark nozzles. The quality and proper spray pattern vs. the former 200k+ mile old nozzles is amazing. The balanced release pressures between all injectors has made idle soooo much better!

Though I no longer belch (fuel) smoke out the exhaust and the bumper/ trunk is no longer covered in oily soot, my fuel economy is still about the same, which is a disappointment. But the 601 engine definitely runs hotter than before the injector rebuild. I set my release pressures across all the injectors to about 117 bar.

So I was hoping someone could say
(regarding fuel economy, timing, IP strain, temperature, etc):

"lower release pressures have these effects....."
vs. the opposite for higher release pressures

Just so I can understand the rationale, and my options

Thanks and Cheers!
