    My poor truck is actin up all of a sudden. Pulled out on the road today on Drive and she was sluggish. Her RPMs fluctuated between 1000-1500 RPMs at 45mph and she shifted very very rough from 1-2 and 2-3 but I didn't notice 4th gear. It was rough enough to hear and feel. She has no shift kit, but is geared to shift 1 mph above stock shift point. I'll get more info about it later when my dad gets home. Sorry for the light description, I'm sad this is happening.

    Turns out when I took off the intake tube today, I didn't plug in the MAS and thats what made it run like crap.
