not sure whats up with the balance rates or the throttle position, this is a screen shot of my truck at idle

Try getting the balance rates in drive after the idle settles a bit....

What do yall make of this, I was messing with the truck tonight just looking at the balance rate and all of a sudden the truck started running better and my balance rates all went to normal. So I drove the truck a bit and it ran like normal, but i do notice that at idle my rail pressure is always higher than it needs to be " desired vs. actual" everything im reading looks like its a bad fpr and/or bad #8 injector. Also my dtc codes have not come back after clearing all of them and running it again.

do you have a DSP5 on the truck? if so check the ECM connetions at the ECM. ive seen people not put them on right or didnt tighten them down
