hi guys,
i have a 96my wrx it has a td05 and z4 ecu as standard mods so far are cat back exhaust straight through, version 7 TMIC, apexi avc-r, slowly saving up for the apexi pfc, will i do any damage by fitting the injectors early and a walbro pump.

 

If you drive off boost then no.

 

I think you can get away with fitting the walbro pump but the injectors your best off fitting just before it gets mapped.

 

as above absolutely no point in fitting them until just before the remap.
