    I’ve recently installed a gt3071 turbo with jbr 3.5” intake fmic injector seals etc. I’m running a CS hpfp and seems like during tuning it only hits about 1767 psi and the grams per second seems at 367 high and afr is way low (8.67). Can anyone point me in the right direction to trouble shoot this ? Or has had similar issues? I’m going to inspect the hpfp, fuel relive valve and what not tomorrow. I attached a log down below

    You've got knock enrichment and fuel pressure dropping. Who's tuning this and how far in are you?

    Also leave the other shit alone for now and answer the above first; do the KOEO PRV test if you want but don't go pulling parts out or you could make things worse.

    Then you're not done being tuned. Give it time.
