Ok here it is, i took a 1400 bored it out, put in mahle low compression forged pistons,im using a garrett t25, a fmu, is a rising rate regulator, so for every pound of boost it raises the fuel pressure accordingly by the ratio the specific unit is....i just want to know know how i can address my fuel issues, if you can recommend anything, it would be greatly appreciated

So you've turbo'ed a 1.4 SPi.... Ok .

Proberbly best of like you say getting a second injector to help the other one out. Ideally you'd proberbly be best swapping the inlet system completely for one with MPi, and then have your 5th injector to help that out. Thing is, it depends how available engine parts are in Jamaica .

you have not even said what your fueling issues are.

Ditch the spi for sure.
