Not really needed. Your LS3 manifold flows great! Unless you go with a big cube motor there will really be not too much of an advantage going with another intake. Your money will be better spent doing something else.

The LS3 manifold accounts for five hp over the previous LS2 design. Save your money

If he wants better flow, just slap on a blower that will pick things up a tad
