if you were running stock everything but had a 255lph fuel pump, would you need a tune for that? or would the computer compensate? dont post unless you are certain please. thanks.

For the 96 in your sig the return style fuel system would not increase fuel pressue. So no tune.
More fuel volume but not pressure. The regulator governs pressure not the pump.

True,

But I've heard of 255HP actually overrun the stock FPR on a TON of different cars.. Some don't.. I wonder if it comes down to the condition of the stock one... That'd only be at WOT though...

you have a bypass... the excess fuel just flows back into the tank...
