FBO w/ Stock Turbo (is20.) On Arob's 13th revision.
Part 2 of HPFP Test.
Filled up tank with 93 and 2 gallons of E85, resulting in a rough mixture of e15 ish.
Test yields semi-inconsistent results, fuel pressure seems to be fine initially, it takes a small dip around 4200 rpm to 170 but car doesn't cut. Right around 4800 rpm it takes a bigger dip to around 140 and cuts.
