93 Octane

Car feels ok, doesn’t give the pull you back in your seat but it’s ok, just my hpfp doesn't look so great at high rpm, high pressure fuel pump are with sparks plug gap at 0.022” new oil change done yesterday. Not sure if it’s mechanical issue due to lpfp seems ok, looks like fuel pressure regulator starving hpfp.

Auto log started at ~3k RPM
