Anyone have numbers on what an intake manifold swap does for tbi engines?

so spend 500 on a manifold with very minimal improvement..oooooooor hop on marketplace find a used carb one and buy an adapter off ebay and get more improvement for 1/4 of the price? so to your point even more gain with a carb intake. just hop on facespac and find a carb intake and the adapter for a 1/4 of the price. cost vs efficiency.
