Considering Eaton swap and have 3.1 upper and #2 Lower. Will this make too much boost for stock motor or I'm good?

That combination will give you between 14.5 and 15 lbs. boost, IMO, getting up there for a stock motor.

Stay below 13#. Even 13# is pushing it.

You also have LT's and I don't though so I won't have to dial it back as far if I made more. I went with the setup because I figured it put me right at the numbers I want and be DONE with the car.

A little high I think. Heck, I just made 466 with LT's at only 9.7#'s!
