I have an L83 with a TSP cam +32 fuel lobe and just installed a turbo. Today I did my first pull and rail pressure dropped very fast at 5psi on e70. Anyone tune a boosted L83 on ethanol that knows what the hpfp should support? Just trying to determine if I need to replace the intank pump. Fuel pressure just dropped so fast, I am leaning towards the in tank pump. Log attached. Thanks.
