I have near -0.6kpa vacuum at idle and hits steady 13psi under boost on all gear except first. I tried to push it on first and it just feels like all motor. I stopped revving at 5k rpm. Tried to search around but got mixed answers.

Some said it is normal since there is not enough load.

I have following set up:
stock s14 sr20
Defi boost gauge
HKS acutator
stock boost soleniod (correct vacuum)
exedy lightweight flywheel
stock exhaust
tomei manifold
others (not related to this topic)

any comments welcome!
