Boost Just Dropped Of For No Reason?

[Turbz RB-25]

Hi fellas,

I was driving around last night, and my car felt a shit load slower. I looked over at my power FC, boost was only at 0.84 BAR (around 12PSI). It was running around 17 PSI the day before? what could have happened?

I didn't touch the PFC.... I am puzzled? Any ideas?

We need some details on your car first, model, mods etc.

R33 GTS-T

RB30 bottom end.

Power FC

GT35R

And the rest of the usual mods (exhaust, FMIC, injectors etc)

what are you using to control boost

what actuator or gate spring are you using

Checked pipe work??

Could have a small leak...

Or even a small hose could have come off...

I went into the setting of the PFC, went into the boost menu, and I change the number on the right ( forgot what it's called, but I think its the percentage of how fast the boost controller solinoid moves) to 70%, instead of 55% what I had it originally. This solved the problem.

Let me know how you go with this.
