I disconnected the vacuum line to my secondary intake runner today. I dont think I felt a differance on my drive home.

How many of you have done this mod? Did ya feel it? Gas mileage effects?

made my intake louder. i barely run my car at higher rpm's where that mod would have made a difference. i had the same crappy gas mileage w/ it and w/o it

I have the mod done. I feel a little more power from 3500-4800.

Makes no difference at high rpm's because all 8 intake runners are open at anything above 4800 rpm.

i mean, not that high

i do most of my shifts at 3k - 3.5k rpms
