When I purchased the GU 3.0 (2002) it already had the NADS installed.
The boost has been limited to 16 psi.
Just wondering what others have set theirs to?

16psi is a good figure and if you have no problems leave it at that I say
I run about 20psi maybe a touch more with no problem as well
If you want to make it more efficient fit a tigged and tested OE IC and a bigger
scoop{ARE}

The best way is to set it just below the limp mode limit. Some hit limp mode st 16psi, some with go higher to around 20. Best way i reckon is to keep increasibg the boost until you hit limp then back it off just under this.

In the words of Pauline Hanson...please explain! What is the 'limp mode'?

Ok. Limp mode is a, stupid and uneccessary, over boost safety thing that Nissan implement. So basically when you hit limp mode, all power to the motor is cut, and the only way to get the power back is to take the foot off the pedal and then back on again to regain power.

Ah... the rev limiter that bikes have.
Why so much history of 'grenade' patrols if there is a limp mode?

I have been following this on a recent thread. It is something for my 'later' box.

you can also buy bigger air flow meter housings from HPD

They don't grenade from over boosting, as many think. Its usually caused from the ECU under boosting creating excessive cylinder temps, creating heat stress fractures, or cracks in the pistons. There for eventually letting the grenade pull its pin. Poor ECU control of boost is a major player, hence using a manual controller, among a few other things.
