I'm currently at Dynosty getting my car tuned and we ran into the same issue.

Have you looked at your fuel pressure gauge to see if it's falling off on the top end.

That was my issue and we found the OEM top seal would not fit snug on my DW pump and the theory was that fuel pressure might be falling out from there. We changed out to the new Walbro 400 and the issue went away.

Now my issue is that my pressure is slightly higher (even with a CJM Stage 2 and swirl jet modification) than we would want it at idle but we are tuning around it.

Well to be honest I was kind of annoyed when they told me that they threw in another walbro pump because they didn't even ask me... I would've done away with the A1000 and Walbro and got a 340lph or 400 like yourself.

Oh well I just want my car back. If that doesn't fix the issue I'll be pretty livid to the say the least.
