the standard reg could be past its best, try a FSE adjustable fuel reg or something similar

silviagod has had good results will the cheap jap ebay ones


are you the guy off locostbuilders??

is the fuel pump wired via a relay? Also i may be wrong but did i read somewhere that the standard ecu map for the s12 runs the injectors at upto 136%?

i'm not using the silvia ecu, i'm using megasquirt much easier for mapping.

pump wired direct to dedicated relay.
