I have a 2013 Grand Sport 6 speed with a v3si A&A kit. Built motor, full exhaust and most supporting mods.; 3.8 pulley @ 10psi on a conservative tune. The only big upgrades I haven't done are ported heads and intake manifold. I'm wondering if anyone has experience upgrading the intake manifold from stock on a similar setup. What power gains would be expected? Not interested in decreasing pulley size just yet if I can get descent gains from upgrading the manifold.

Stock manifold is all you need

No need to change. Stock is fine.

Thanks. Read some other threads and looks like the general consensus is to use the stock manifold. Can introduce problems with leaks it seems with some aftermarket manifolds
