Quick update I swapped the harness today and the roughness stayed the same :-(
We tried to knock out a tune today as well and ran into some fuel issues for whatever reason. I'm going to take out the fuel pump tomorrow and see if something is going on with my pump pressure is dropping off once we start putting 22lbs+ of boost. I've ran 26 on this turbo and exact fuel set-up as I currently have without issues. So on to more trouble shooting I have Walbro E85 drop in pump, stock lines to the fire wall, All -6 steel braided lines with Aeromotive fuel rails and FIC 2150 top feeds, AEM FPR.
We also set-up the car into a hybrid MAF/SD system to see if it can alleviate the roughness issues but in my opinion it seemed to make the car worse. I drove it home on one of the low PSI maps and could barley keep it running so I had to grab a different map from my tuner that we used before today in order to keep to car drivable. Problems, problems, problems story of my life. I don't have any graphs of the dyno session today but it more or less felt like a waste of time and money. Maybe I'm just tired from the day in general /rant!
