Standard Boost Pressure Without Restricter?

[BrynDETT]

Hey everyone, finally got my car tuned, just trying to work something out.

engine is a standard r34 rb26 with front mount, dump pipe back exhaust and a microtech ltx12.

using a hks evc, (forget the number, 5 or 6?? the newest one) the car wont run anyless then 16psi stable. when set to anything lower then 16, it just creeps up to 16, but set at 16 or higher it holds it there,,

it was tuned for 16 so its not a problem, just would like to run less for when im just plodding around. i have seen from a fair few sites 1bar is stock for r34 without the restricter, so i guess this makes sense, allowing for 1psi increase with free flowing exhaust..

can anybody confirm this or does anyone think there is something wrong?? thankyou

Technically there is 2 restrictors (in BNR32s at least), 1 by the solenoid in the rubber hose indicated yellow band near the solenoid and another that is part of the wastegate hardpiping that can only be bypassed with new hoses.

As for stability under 16psi it's most likely the EBC's gain setting is way to high as the gain was likely dialed in for 16psi.

nah it wasnt the gain, the tuner bypassed the ebc altogether and the actuators still went to 16psi.. and the engine is in a silvia so there is none of the standard restirctors

nobody have a standard r34 gtr with the boost restrictors removed??
