A RRFRP definitely will improve mileage for a 16v turbo when compared to a 2.8 or 3.0 fpr, if one has replaced the stock 2.5. And if all you cared about was mileage, I guess you could reduce the RRFPR base pressure below 2.5 and even beat the 2.5 fixed FPR mileage, while still having acceptable performance.
Back to your question.
I'm not sure about the fpr on an 83gle/CIS injection and this is a guess. If there is an adjustable rrfpr available, you could also set it run at a lower than stock basic pressure for a leaner idle and still get a rich enough mixture under load. There is a good chance that the NOX emissions will go up at idle, but maybe you don't have to pass an inspection for NOX. This seems like a long climb for a short slide. Maybe someone who knows more about the 8V CIS injection has a better answer.
