Default LS2/4L65E reving slowly

Hi there. I have been driving with my LS2 corvette conversion for a while. Best engnine ever. However, when I rev the engine with the tranny i neutral, the engine drops down i revs pretty slow. Slower than my former 509bb or ls6 454 that I was driving with before.

How come is this?

It speeds up very fast, but drops slowly. If the engine idles and i pres the throttle pedal fast, the engine kindda "burbs" before it starts taking revs?

I have used a LS2 crate engine with LS controller kit, plus a new 4L65E with controller kit as well. All new from gmpp. Drives like a rocket
