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.
Fuel pump and injectors would give some insurance. Assuming a good quality tune is done to compensate for the injectors. If your running the injectors at close to max duty cycle there is more of a chance of one going out.
Also boost gauge, wideband and egt gauges always reading so you can monitor your could help to prevent a bad situation(shutdown if see bad readings).
