a little while back, I posted a thread on here about a stumbling issue w/ occasional backfire.
Breifly: Under load below 3k rpms or when pulling out from a dead stop. It started out kinda minor, but over the past few weeks, it just got worse. Now it will do it up near 4k once in a while and it runs like total ass above 8k ft....good thing I live at 6k.
So far, I have changed the fuel filter, put the plug wires back to stock, spark plugs changed, cleaned & checked the MAF, reset ECU, and its throwing no DTCs.
Took it to the dealer and they called me to tell me they are starting to look at it....ok....10am. I wait to hear back and at 2pm they call to say:
So now I am waiting it out. I have some data logs sitting here to look at, but I am a n0ob at that sort of thing....the fuel pressure seems kinda wierd to me, but like I said...I am a noob. I am hoping they will replace the fuel pump, but its doubful.

"well, we have tried a few things here; checked the intake out (which is FS coolFlo), there was an update to your ECU so we reflashed it, and now it actually runs worse."
"we have our best guy on this now and he's having a hard time figuring it out, we may have to keep it overnight."
