Default boost trouble

Hi, I've just finished my JDM STi version 4 type-ra swap into an impreza rs 2000 and my boost peak at 15psi to drop at 14.5 steady... I think it's supposed to be higher (like 17-19 appr.)


-lightened flywheel
-Helix turboback (3")
-Ported VF24 (original turbo)
-turbosmart bov
-aftermarket air filter

1st. What could I look at first for this minor boost problem??
2nd. I'd like to know originally what's the peak boost for a jdm version 4 type-ra!!

Thank you for your help!!

All go and no show...


You might have more luck in the conversion forum. Most of the guys here have USDM turbo motors. More people are probably familiar with the JDM setups over there.
