    I have a Black Bear tune now, and will get them to update it once I get the header issue taken care of.

    When I got my 2012 last year and before I turned AFM off with a tuner, I noticed the truck would only go into v4 mode after letting off the gas. Even when cruising on the highway at a steady speed it would still be in v8, unless you lifted off the gas.

    Seemed pointless to me, because minimal amount of fuel is used on decel anyway.

    Cleaned the Maf sensor and the throttle body because it's been feeling a bit less responsive. Looked inside the intake manifold to see how much oil i had pooling but i couldn't cause of how it was designed. Never seen that. I remember on my ls1 i could see most of it. 20191108_095152.jpg

    How much would things change if the hole was bigger? Looks restrictive
