Have you guys with Hallman MBC had this happen to them before?

You're boosting from 3rd gear, you start off at around 3500rpm, going all the way to the redline.

Your boost seem to hit 21psi, but you have it set to 22psi. sometimes it goes up a boost or so more.

Now the boost hits 21psi but as you stay on the WOT longer, it'll start to go up at around 5000rpm to 22psi instead of hitting 22psi right away.

Boost creep?

maybe the 272 intake / 264 exhaust setup messing up?

I have stock wastegate, but I don't really know the extent of how much whp they are good until.

I'm running around 320whp now.

just wondering. It doesn't bother me but it does worry me a bit when the boost starts to go up slowly few seconds after WOT.
