Boost stops at 1.4bar - N75?

You need an air line bud, a pump will not do it.

The knock sensors are bolted to the side of the block below the IM. Loosen the bolts and re-tighten to the correct torque of 20Nm.

I will try that, I did notice today that there is a bit more shaking when idling.

Can I use inflated tyre for the boost leak test, as I don't have tyre pump?

Try re-torqueing the knock sensors.

What do you mean by that?

[newsh]

Try re-torqueing the knock sensors.

No

Thanks

I didn't do boost test, because I thought car should judder and have sort of loss of power. .

Just do the boost leak test and stop wasting our time.

Please.

I use dashboard boost meter, and that includes atmospheric pressure of 1 bar, so whatever you see on the dash minus 1 bar is your absolute pressure.

No, its the relative pressure. Absolute of 2.2 Bar (which even a stock AAN will do on over boost - with no leaks). 2.2 Bar = 31.9 psig absolute. Minus atmospheric of about 14.7 psig (1.013 Bar), yields 17.2 psig relative = 1.18 Bar relative.

Gauge pressure is starting at atmosphere as 0 - so atmosphere is 0, 1 bar boost would read 1 bar guage
Absolute is pressure + atmosphere - so atmosphere is 1bar, 1 bar boost would read 2 bar absolute

No

So the type I have is a gauge type with vacuum feed T'd into the ECU is the reading on this correct when it reads 1.5 bar or should I minus 1 bar

OK what does this mean and how is it tested

[hunker7]

Isn't 1.5 bar good boost, mines chipped and reaches around this, only got to 1.2 standard

That's gauge not absolute.
