[GTRVS2]

hi all having a few boost problems with my stock R34 GTR VS2

1. boost display on dash does not always work ie. shows nothing at all and when it does decide to work the car only boosts to 0.3bar

2. my PCM Valve has a white band on it i can not locate the yellow band/restrictor

3. the car does not pull as hard as it used to ????

4.does anyone now were the boost preeure sensor is?

all this happend after i manually adjusted the boost from the display inside the car droping it from 0.5bar to 0.3bar. when i put it back to 0.5bar it just stayed on 0.3bar ????

any help is much appreciated

I didn't think you could adjust it either.

If your sitting in the car and looking at your bonnet, the sensor is on the right guard. I had a similar problem, I replaced the sensor $280 and it was fixed. Jsut tap the sensor and see if the reading shows on and off.

Go to your right guard, on the very edge you will find a bracket holding a black sensor, that is the boost sensor.
