One of the things PowerFlow can do is flow match the ports on an intake manifold to be within a couple % of each other. I would be interested in seeing the results of this process.
I would also like to see the performance gains of flowing the exhaust housing of the turbo.
Everything else probably would not meet the price/performance benefit ratio that other modifications are yielding.
