I don't buy it. You're not going to pick up that kind of gain on a turbocharged engine just by reducing intake restriction.

The turbos are reaching peak pressure with the stock intake based on waste gate control. Reducing intake restriction may allow the turbos to spool a little quicker perhaps reducing lag and adding a little low end torque (you will reach peak boost sooner). But max boost remains the same. You are not going to gain 32HP without increasing boost.
