StopSign

So, when I'm cruising at highway speeds, the accelerator is jittery once it needs to get on it a little; instead of being smooth adjustments, it's almost on/off.

Here's what I've changed: GFB DV+ with spring; open airbox; afe dry filter; new high pressure fuel sensor; now run a few gallons of E54 with 91.

I'm thinking it's the DV; GFB says the spring can be removed to function as the stock one. The only weird thing is that I ran these mods for a few days with no change until I was on a long road trip; second half it started.

No codes, no clues. I ran live diagnostics while driving the night I noticed it, but couldn't discern anything. Other than this little thing she runs better than ever.
