VQ35DE: change in power at 3500 RPM

Postby picoman » Wed Jul 25, 2018 6:15 am

I believe 3500 RPM is the crossover point for the variable length intake manifold.
Is it normal to feel a slight flat spot in the powerband at 3500 during the crossover?

It feels like a quick 5 hp interruption in power between 3400 rpm and 3600 rpm if that makes any sense.
