Recently converted to e85. Turbo tweak 95lb injectors and chip. Have a steady 43psi fuel at idle vac unplugged. The problem is under boost (20lbs) my fuel psi is only getting up to about 50-53psi. My AF is leaning way out. The car misses and backfires under full boost. I’m running a new DW300 pump with Hotwire. Stock lines. Any ideas? All research says stock lines will support 95lb injectors. With the slight exception being the return line restriction which would cause a spike in pressure which is not my problem.
