[EDFHOBBIES]

Wifey has an eforce on her SS I gave her my lt4 fuel parts. She went from 580/580 to 615/666 she had always through a code low fuel rail pressure especially when no lift shifting. Hadn't had any codes since she got my goodies.. DSX lowside aux, lt4 hpfp, and lt4 injectors. Now the compression is the issue.

At 4000 rpms I got serious cutout aswell with the lingenfelter big bore pump ,dsx lowside, and plus 30 injectors. I extended the drop to about 6000 with the high flow ck valve and fuel line work by the hpfp. But this was with cam lobe 38% and full e85 near 900 to the wheel. On 93 it was solid to 850 no presure fall.

Now I'm port injection and lt1 fuel part 840/1004.

Hopefully this gives ya an idea.. I think w lt4 stuff and aux you should do better than an eforce.. or maybe the 6 gen eforce have gotten better.
