what does ur boost gauge read when cruising?
lets say your in your final gear cruising on the highway at 3k rpm, what does your boost gauge read? vaccum or is it at 0+?

my boost gauge is usually at 20 vaccum just cruising at 3k rpm (light on the throttle), just wondering if its supposed to read boost or not.

if im easy on the gas and shift all my gears at say 4k, i wont read boost, unless i floor each gear... is that normal?

also depends on if you turn on AC or not. turning on AC will lower your vacuum a little.

how's the SC? having fun surprising some big muscle cars? still have the N2O with you?

the SC is pretty fun, it makes dipping in traffic easier since the car pulls so muc harder

the N20 is still in there too, i'll take it out when someone wants to buy it from me

I was able to do a fast run from a dead stop early Saturday morning along an empty stretch of highway and I saw 9 lbs of boost. Its funny how I see only 6 lbs when I boost while already in motion.
