    No.. unless your current tune is compensating for a pump that doesn't have sufficient flow.

    no, i'm just on a stage 2 TP. I want to go stage 3 at some point and just wanted to know if having the pump in would mess with the tune at all.

    Took me almost 2 hours to do a fuel filter relocation. Stupid old hoses were a PITA to put on new filter.

    No, installing a fuel pump will not require a tune. However, to get any benefit from it you would need a tune and stage 3 (as you plan)
