I have a 5.7 with Comp 270 cam, shorty headers and high Flow cats, stock throttle body and 8psi magnuson it's making 570 rwhp. What gain should I expect with long tubes and 90mm throttle body? Thanks

90mm... negligible unless you are starving your motor of air. 5-10hp maybe a little more because you have FI.

Longtubes perhaps 10-20 depending on brand.

Both depend on how good of a tune can be created.

Might just look into a Hellcat 92mm if it will fit after adapter. I would guess 35-40rwhp.
