My LLY injector balance rates

Just picked up a edge cts today and checked my balance rates. Truck has 75k on it. Number 8 seems a little high but still in a safe range?

It was in park. I did see number 8 go up to 5 at one point. I shut the truck off and then got this reading I took a pic of. Not sure why it went down just from restaring my truck.

So these are the numbers in ImageUploadedByAG Free1358378520.040976.jpgdrive. Did see 8 go up to 5 at one point. Injector 5 also went up to around 4.5. From searching around the forum, it seems the first place I should look is the wire harness that rubs on the alternator? I guess that can throw weird numbers if its chafed?

Any ideas?

image.jpg these arent in spec but seem to bounce around a lot. Any ideas as to why. I ran injector cleaner through it to see if it would help.
