Boost Decrease!

[TrentGTR]

I have a stock R33 GTR, im running 14psi peak, but after a while (after hurting it quite a bit) the boost drops to 7psi peak!

Is this normal? Then when I turn the car off and let it cool down for lets say an hour, it will go back to running 14psi peak....

is this normal? Any1 else having this problem? Should I worry?

thanks!

Not normal but could be alot of things. Seeing it is in heat maybe its a flexible pipe sucking closed.. It'll either be a problem with boost control itself or a problem with getting the charge air to the engine.

Good luck

I think you will find your computer ( stocker) cuts boost to actuator pressure because its leaning out up high to prevent engine damage .

You will find if you was running stock boost that wouldn't happen.
