would upgrading the fuel pump at stage 2 remedy this, or at least be some insurance against this possibility?
i just picked up a maddad bellmouth catted DP, and am also concerned with affecting the reliability of my 08 wrx when going stage 2. like the OP, i don't plan to race, just want to up the HP of my daily driver.
i have been reading a lot about how monitoring the IDC is important when upgrading turbos, thus the importance of simultaneously upgrading the fuel pump and injectors... so this has me thinking i should perhaps upgrade my fuel pump before installing my DP.
