Question about 2.5 acceleration
I am curious as to what changes the 2.5s performance when it hits 3500 rpms? I am aware of the dual stage intake but I thought that didnt kick in until >5k. When I am driving may car and it hits 3500rpms it almost feels like a 4 barrel kicking in. Is this normal or is it that something is not working correctly at the lower rpms?

It's a 3 stage manifold, Idle - 3299, 3300-3899, and 3900-redline. Stage 2 is pretty noticable but stage 3 is by far the biggest change in engine sound.

I think it's the torque, we peak at 3900 rpm, and if you look at our torque graph it climbs really sharply from 3000 to the torque peak, maybe that's what you are feeling. I don't really understand why our torque peak is so low with a 6800 rpm redline. We would accelerate much faster if the torque peak was later.
