I think you are on the right track going with the inline 255lph pump, adjustable FPR and a fresh set of injectors. If you can let the car sit, you can send out your injectors for cleaning/balancing, certainly cheaper than new units. The stock units can easily handle 300rwhp with added fuel pressure to support, so no need to upgrade yet. Make sure the power source for the inline pump is robust and is using properly sized wire, so you don't get a drop in voltage at full tilt and therefore reduce the output of the pump! Since the upgrade was done by the PO, you don't know what you have at this time. Keep plugging away and you will get it right.
