A buddy and I are gonna try to tighten
it up a bit there and switch to a 5lb cap.

Why switch to a 5 lb radiator cap (I assume you are referring to the
radiator)?

At the lower pressure your radiator will boil over at a much lower
temperature. If you don't swap out the thermostat to a much lower
temperature model you may make matters worse instead of better.
