1990 GTR

M's Intakes
Trust hardpipes / Induction Kit
Trust Intercooler
Blitz blow off valve

Stock ECU
Stock Turbos
Downpipe / Decate / Catback all done
Splitfire coils and NGK irridium plugs

Car boosts about .6 bar right now (thinking because of the less restrictive intercooler piping?)
Removed brass restrictor. No change. Even with ECU reset. Running a Greddy Boost Gauge to confirm boost.

Everything else is stock. Stock boost solenoid in stock location. Should i run a manual boost controller to see if i can get boost to increase? Or possibly another issue. Car runs very well.

I would say the best bet would be buy an after market ECU say Power FC and get the car mapped properly buy a tuner.
They will up the boost safely adjusting fueling ect,ect for you when they map it,
a lot safer in my opinion or it may end in tears with something expensive going pop.
