It's a great tool for the average DIYer, which is why we worked so hard with Jay (owner of AE) years ago to make sure the Powerstroke coverage was as good as it possibly could be. Jay spent hours at my place testing numerous different trucks and comparing functions to the Ford NGS and IDS...
It's not clear from your posts, did you get one of our kits or someone elses?
One way to diagnose whether the problem is related to the RRK (which it rarely is) is to locate a section of the flexible/rubber RETURN hose on the frame and pinch it closed with hose crimp or soft jaw pliers. Then...
With stock injectors, even with a hot tune, you should have no problem holding pressure. If the pressure is dropping, there is some kind of fuel delivery issue that is reducing volume (weak pump, restriction between tank and pump, etc).
It was nice finally meeting you as well.
Unless I can find some serious time to get out and race the truck, it will remain for sale. I hate looking at it just sitting here doing nothing most of the time.
Yes, our race delivery systems would replace the stock pump and work with either of our regulated returns as well as any other RR out there (though I can't guarantee all of the needed parts are there if using an RR kit other than ours).
A high volume low pressure lift pump feeding a stock pump is not a bad setup, but I would think it should support your 205s with minimal pressure drop...but once you go to the 285s I would anticipate a problem. The stock pump can only move so much fuel. I would anticipate it becoming a...
