As for the fueling issue, I’m pretty sure it’s resolved... root cause? I’m an idiot.
So when I bought the truck it had the II dual fueler kit already installed. I noticed the harness wasn’t like for every other dual pump kit I’ve installed, such as the one pictured below...
What I had resembled the picture below... I knew fleece made a dual pump splitter...I had never looked into them, but I was assuming that’s what this was, as it looks nothing like the PPE controller I’m used to.
In reality.... pictured below is a fleece dual pump splitter. The picture above (which I have) is a fleece dual pump controller.
In the end... I had my tunes written to work with a dual pump splitter, when I in fact have a dual pump controller. This explains I had problems before and after the injector swap.
Now I haven’t driven the truck yet, but the funky idle issue is definitely fixed. I’ll be driving the truck in the next couple of days to verify the surge is resolved, but I’m 99% sure I won’t be seeing any issues.
I feel like an idiot, but at least that’s one thing I have lined out and I can start logging/testing finally.
