I'm reading as many threads as I can find but getting mixed comments.

A stock jdm hawkeye, if I uprate the fuel pump would I need to map it? It hasn't been mapped and am planning a map when I get the exhaust done.

Possibly run a little rich due to extra flow if your increasing the capacity of the pump (even though in theory the regulator should keep that in check) but should'nt do any harm. Put the original sock on the new pump if you can far better job.
