Well here is what I have to offer. This is a 1/8 mile pass not a 1/4 as I don't have a 1/4 mile track near me. You can see the MAP dip as TM kicks in. But before that you can see that the "boost curve" is not much different than yours. Now I will credit it to the fact that do launch in 2nd gear and have a stall converter in it. But that is my point. If I can leave the line making 5 psi and within 2000 I have 15 the torque will feel "instant". A proper setup, and fast car is more important to me than feel. And I will bet there is no more "instant" feel than leaving the line with 5psi and a 75shot kicking on in 100 RPM.
