What would be causing it to do that though? And how would I go about fixing it?

R33 Rb25det not performing New to the forums not really sure if this is the right section to be posting in but I've spent several hours raiding the forums and can't find a solution anywhere. I have an r33 rb25det it has a bigger fuel pump, front mount intercooler, super spark coils pack, 3.5" turbo back exhuast and a boost tee. It's running 0.74 bar of boost but it feels like it's not even boosting I can hear the turbo working and the gauges are reading 0.74 bar of boost. It smells like it's running real rich and has recently started to really chew through fuel. I have changed the spark plugs had them gapped correctly and the coil packs are 2 months old. What could be causing it to feel like it's not on boost and being real slow?
