no... Generally you will have an aftermarket FPR if you go turbo and don't have an engine managment system (mpi, ems, microtech, haultech, etc...) Forced induciton requires more fuel and fuel pressure which is where the aftermarket regulator comes in- it works inline with the stock one.
So, if you only have the stock one- then that's all that will need to be replaced. No worries.
