The truck runs good, the engine is just going through an additive package swap and a cleaning of the oil system. Still on the third oil change and since after the first oil change, my issue with stiction has steadily improved.
I.e. The throttle response and mileage have steadily gone up, cold starts are much easier even with me running a non-inductive heating flash.
For those wondering, I severely dislike how the latest flashes with inductive heating covers up and compensates for bad injectors. This is why I had my FICM flashed back to an early strategy without inductive heating. As I've mentioned in numerous threads, these don't compensate for bad injectors near as much as the newer calibrations if at all. So if you have a bad injector or stiction it will be obvious. If you're trying to use a product like Hot Shot Secret and AR9100, the FICM compensating for the weak injector almost defeats the purpose since the injector may not be running at full capacity to help clean up the stiction. With non-inductive heating flashes, if you run some HSS or AR9100, and drive the truck like you stole it, both products work as advertised unless you have an internal hardware issue with your injector.
Granted, I live in Texas and it rarely gets below freezing, but this is also why I plan on running a full synthetic; much easier starts even without a block heater.
I think I over emphasized and may not have explained the way they did...

) and when I went to do my 1st oil change, looking in the oil fill cap at the valve train, it was obvious the car probably ran 30K miles on the original oil! 
I wanted to run a solvent through and clean all the sludge out, but a friend who was a lubricant Chemical Physicist, suggested I do short, no more than 3K oil changes and swap out one of the qts of dino oil with Mobil 1 of the same viscosity (that was back when M1 was full PAO). It gently and slowly cleaned the engine without clogging any critical passages, to where by 80K or so the insides gleamed like new!
I was impressed -- sold that car with 140K on the clock and it used hardly any oil...
Love that PAO and also the Ester based syn, just pricey is all, so make sure you are getting it for the right reasons: cleaning is one, but high temperature operation would be another, and you should be able to run it longer, etc...
He said even with the 15w40 you could easily run to the 7500 mile interval recommended by Ford. I'm going to try it next oil change and have an analysis done, to see how my truck does with the 15w40 at 6000 and 7500 miles.
Bottom line, I like Schaeffers better than anything else I've run in either of my trucks. Now I just have to get my 7.3 off the junk it's on now...
Agreed...
Heres food (oil) for thought...
My dad is a machinest and is in charge of about 20 machines worth over 50 million dollars. Hes the main guy where he works... he once told me that if they dont run Mobil in their machines it will void any warrenty. Theres a reason im sure.
I use shaeffers grease in all my equimpent. Its good stuff. I have never tried their oils or even compared specs to Mobil. I do run the T6 syn in my larger trucks and have it tested every 5k. Ive known guys that have done almost 100k and just spin on new filters every 15k and it tests out good. I personlly would'nt push mine that far no matter what the test says.
As to knowing it feels different around 5k.. yep.. i can tell. Cold starts take longer to warm up.
