Yep stock tires, we both had p-zeros. I tried searching for the original thread but I couldn't find it. I think Blaine might have had the air filter out but I cant remember. I do know both trucks were dead cold, he was trying to teach me how to shift... put the gas to the floor off the line and never let off. He was beating me to 60' 1.89ish I think, wears the clutch out quick launching like that though.
