Hello everyone. I have a 2007 Cobalt SS converted to turbo with a zzp kit and tune. I'm trying to fix the issues with the tune that I have sine it's set up to be a returnless fuel system but I have a return style. I have read up on SJSchafer's guide on how to set the fueling tables up properly for a return style, along with the IFR and modifier. However, I am still having problems getting the car to a point where it will at least idle smoothly.
Any help would be greatly appreciated, and I will provide logs and tunes for analysis.
Thanks in advance.
