More parts rolling in. Got 2 new 195* Ac Delco Tstats from RockAuto, along with rad hoses, reservoir cap and hose, feed the beast components, a new 6" tip to replace my 5" (because bigger tips = more power right???

) and also a new hinge/latch assembly for my new tailgate too. Not pictured is the 3/8" fuel line and barbs, Cummins fuel filter adapter, and Napa fuel filter adapter. Hope to have the Raptor either the end of next week or beginning of the following week.
Update on the injection pump stepper. Put a new (used) stepper on tonight, seems to be working okay. Cleared the CEL and drove it around a bit, no more CEL. So I believe the stepper is doing what it is supposed to do. However the truck is still sluggish, EGT's are still high, and boost is still low. I don't think its a boost leak, I think the computer is still in need of a TDCO re-learn. I found a KOKO procedure but have had no luck with it. I have tried:
Key on, accelerator down: 45 secs
Key off, accelerator up: 30 secs
and
Key on, accelerator down: 45 secs
Key off, accelerator down: 30 secs
No luck with either attempt. Looks like it needs a TimeSet learn from a Tech2. Not too bad since the truck is still drivable, just need to play the waiting game. Either way, good reason for me to leave the lead foot at home and drive a little slower haha.
