variable intake system

I have a question on the variable intake system, it opens the second set of runners at 4800 to 5000 and with the 6250 redlineits kinda short. isnt there a way to make it open sooner? I used to have a 86 toyota carolla gt-s with (tvis tuned variable intake system) thats where honda got the idea on the integra gsr and now nissans qr25 motor. I found that by putting a smaller vacuume pot on it it opend quicker and sooner, but i havent been able to get much info on nissans variable intake system. to see if this same method would work to get the second set of runners to open a tad sooner getting more air into the engine. thus more power...

on the toyota it orriganally opened at 6 with a redline of 8 after i swapped the dashpot for a smaller one it opened at 4600 and really made a difference.

hopefully there will be a way to do this with the qr25 cause once the second runners opens it just really comes to life!
