If I understand right the fpr will still maintain the stock pressure I will just have more volume of fuel going through the return line.

this will also be the last thing I do before I put in the turbo, so I will only be running stock for a few days, a week at most. since I am doing it all in my driveway I will have to do it in stages, the obd1 conversion and test fit 1 weekend, radiator upgrade and fuel pump swap another weekend then turbo/injectors/fuel and egt gauges, the next.
