Ok within the past month Ive installed new cups, stage 2 swamps split shot injectors as I had cracked cups and everything went great except I was getting a slight romp at idle so I figured it was the ts6 I had with canned tunes so I sent a new ts6 to Swamps for the free reburn for the injectors but before that came back I installed a new icp and it got a little better so I recieved the chip and just installed it and the injectors are a ton more quiet with the Swamp tunes and the tunes work really well but the romp now is more then before. The engine was at operating temp so I haven't tried it cold till tomorrow morning. I then went and installed a new black cps I got off a neighbor that had it for a spare and sold the truck but still the same. Besides the romp at idle and a bit of a miss right at first when reeving up in park it runs great. It didn't have this romp with the old injectors and they had 257k miles on them so id believe it shouldn't have it now. I run rotella t6 5w-40 full synethic due to it helped the old injectors when cold but could it cause these stage 2s to do the romping because its a lighter oil? Could it be the hpop is at the end of its life as its original with 257k miles on it? The ipr was replaced with a oem one but man that was over 5 years ago could it be going bad? Id love to straighten this out as it runs great besides the romping and slight miss when reeving but the miss disappears right at 1100 rpms and revvs right up with no stumbling. Any help is greatly appreciated. I have torque pro and the Bluetooth adapter so I can monitor some stuff but does anyone have a list of correct percentages and pressures for individual readings to compare to like ipr,icp,pulse width,ect ect? after 2600 bucks im a bit perturbed as it didn't do this before doing cups, injectors and I also added the riffraff fuel crossover and used an AD injector in hole 8 instead of the LL injector.
