Peterbilt 2015 cm2350 list of issues

[Trey7981]

I read somewhere that new injectors on cm2350 are plug and play is this correct. If not what do I need to do on insite.
FYI after installing the new FP head and metering valve other injectors are failing. Just gonna buy a full set and replace them. $12k for 6 new “not reman” injectors is crazy!! Leak down test lost all pressure into the hundreds in 60sec.
