No Codes! No Lights!

Well…I haven’t myself but hoping with two tier 2s and three or four hookups somebody did? Yes I have had it hooked up during this “halfway” regen for a few minutes when I was driving by the day before….twice, to make sure they knew exactly what the problem was. That’s about as far as it went. Did install a new DEF doser somewhere in this mess and hoping SCR was checked. Ok…….as of right now I have about 150 miles on a new DPF and it hasn’t done it’s “halfway” yet. This is not it’s normal behavior as of late. Thinking it’s fixed but not really. When I had the old DPF sonic cleaned five weeks ago the truck ran perfect for five days before it started the “halfway” regens one after another. So, with the new one I am expecting the same thing……we’ll see.
Also, could a leaky CAC be causing ALL these issues? Building extra soot, high diff pressure, slow turbo speed during regen and so on? Just at a high idle, soaked with soap, I get one golfball sized foam after about a minute. Checked it yesterday. Sometimes at full throttle at about 1400 rpm I see 34 on the MP. Mostly I see between 27 and 30 at the same rpm.
JIMT. Complete new wiring. Everything! About $1600 worth installed myself. Some new sensors but which one or two or more could cause it to be jumping into SCR warm up mode?

Thanks for the help!!!
