The issue is fighting fuel pressure drop on a returnless system. Between the lack of a boost-reference fuel pressure regulator, and the pressure drop in the stock fuel lines, fuel pressure is likely high 30s PSI when it should be 52 PSI.
ECUTEK can compensate for this with longer injector duty cycles to increase fuel flow, but only an additional 20%.
My next plans are to swap to 8AN fuel supply line and at some point a boost reference FPR.

Why not, just install a fuel return system?
