Previous best vs yesterday's run. Fatter torque curve.
Seems as if the curve stays smoother throughout the powerband when using the stock helmholtz type resonator. This can be seen on Z33 dynos as well. All have a small dip in the 5k's, and when we add a straight midpipe, we see the same dip. Stock resonator has friendly inlet sizing AND it's nice and smooth.
Maybe sleeve it so air only goes one way, into the engine.
