Yeah, that is higher boost than stock. It might be a weak chip, or a strong chip with a boost leak.

Default 0.93 hkpa = ~13.5 psi. That's high for a stock peak, I believe. Not sure which chips run that low
boost though, so not sure what it would be for an aftermarket chip.

Where are you reading 0.93 hkpa from? Digital boost gauge?

Default Nope, i dont think there's leak coz i replaced TBB, BPV (710N) and all the hoses that have cloth ...
with silicon hoses, then also changed the fuel vacuum line to silicon. All tied up with wire ties... what else could be leaking?

Default BTW, I'm using blitz DTT DCII and I'm tapping at the line before right BPV... should I be using FPR
line? I heard FPR line is not safe to be tapped

Default 1.5hkpa? Btw, the boost doesnt hold up that long, it's like 0.93 for just in a fraction of sec, then
goes down consistently... is this the same in ur cars?
