With this situation it would be an intake side leak, not exhaust. I found a minor intake manifold to head leak, so I installed a gasket + RTV and now it is sealed to 30 psi. Timing ain't hopping lol.

Colder plugs in and this seemed to have fixed things, just needs a tune. Runs great, pulls fine @ 18 psi. The idle rumble issue has been reduced to just from how I changed the tune originally. (Spark advance was always jerky at idle when I'd datalog it, just because my changes for bigger injectors, VE, and spark at idle, need to tinker with it, but the rumble is coo) Need my HPTuners back so I can do shit.
