Not many will have the balls to say, I appreciate the level of detail that you have done. Please don't install any side pipes with built in steps.
What lights/ codes?

I appreciate that. I try to do the best I can with what I have and know, which isn’t too much. It’s not perfect but ten times better than the hack that did some of the work before me.
And I can’t stand steps of any kind so there won’t ever be ha
ABS I’ve been chasing wires with the service manual to make sure when I gutted the harnesses I didn’t switch a wire in a plug somewhere. Could also be from me welding a truss on the rear axle. Heat may have messed with the sensor. Though I do still have a speedo.
The map sensor also show 5psi of boost just sitting not running. Swapped sensors from a known good truck and the same. So not sure of that either.
Just a bunch of pain in the behind gremlins to chase down.
Why studs for the injector hold-downs? I think that's the first I've seen it done.

What he said^^^
I’ve broken a few rocker hold down bolts before. Ive had the stock bolts stretch easy and snap outta no where.
Speedo will work off abs and/or trans output sensor. Just a though but the ABS module needs the VIN to be programed and matched to the ECM. The ECM you are running now may have a VIN mismatch and be causing your ABS. You did not post any ABS codes but your comment on changing ECM made me think of this. All the modules on these truck look for VIN to match for communication.
On the boost senor. You should be at 1 atmosphere or 14.7 psi give a few tenths with the engine idling. Check the 5V reference to the sensor. On the older trucks.... 06 to give an example. The 5V reference from the ECM is for MAP, Air Temp, Crank and Cam senor, and rail pressure. Make sure all the other sensors are good. You can also check the return voltage from the map sensor. Last but not least is to check your grounds. I have found many weird ground issues with these trucks over the years. I have fixed a few by going straight to ground and bypassing the ECM when needed.
BTW..... Nice clean build. Love the effort you have put in. It is all about the details!
It's some stupid torque like 40in lbs or lower, can't remember exactly. Let's just say they're about as fragile as the injector studs in my opinion.
I’m not sure the exact length for the injectors studs but the only ones I’ve seen are advertised for 5.9 injectors. Which I have in it.

I’ve got a handle on all the leaks. Swapped in a new OD housing and new seal where the rooster comb goes through the case. Haven’t have a drop since. Had a few of the timing case cover bolts loosen and leak. So took them all out, cleaned them and put some permatex white seal + lock on them.
Just made the 650 mile trip to Ohio, saw a buddy then made a stop at Firepunk to have them dyno it. More to make sure everything tuning wise was good because of all the back and forth there was with changing ecm’s and wiring/sensor issues I had. Made a highest of 1074 which is lower than I wanted but I’m more happy it’s running finally and making good numbers. Then it made another 600 mile trip to PA
Did have a electrical issue on both trips though. Every so often when I put up a window, turn on the lights or something that draws a good amount of power, everything starts surging. Lights, rail pressure, air dog. Only does it for a few minutes and it’s fine again. Just another thing to hunt down.
Not sure I’m happy with the cam either. Feeling a stock cam would be better for what I use the truck for.
