I currently have a tune/cat back/intercooler. I'm looking to bump things up but my question is this. If I install an aftermarket fuel pump, will the fuel pressure automatically go up or will I have to tune it to get the pressure I need or will the ecm auto compensate?
Any help would be appreciated

If you get into bigger HPFP and injectors then yes, it will need to be tuned.
