boost/vac questions for people with DH

[MicaSp33d]

I just got my DH the other day i was monitoring boost/vac. I won't see Boost until i really romp on it or at WOT. Most of the time i'm only seeing vac pressure and maybe 3-5 psi of boost even though im rowing through the gears. If i romp on it on the freeway i can see spikes up to 17psi. Is this normal?

yeah you will be out of boost when cruising around town for the most part. the 17 psi is from your forge bpv holding boost better. stock it would be arond 15 or 16 then drop off up top in rpm's. its good to stay out of boost when just at part throttle anyways because the ecu is running closed loop meaning your AFR's will be in the 14 and 13 range. boost and no fuel means boom boom to the zoom zoom regardless of mods.
