Have had a search and cant seem to find the answer, Can anybody tell me what the standard boost pressure is for a kkk turbo?

Currenlty have an over fueling tuning box and just fitted a boost gauge and it is reading 1.7 bar max and holding there drops down to about 0.5-1 bar. Seems a little high

stock is 1.3 bar on stock map. It shouldn't be tailing off down to below 1 bar until you get right up to the redline.

Cheers for that. Only drops to .5 when pootling around. Holds at 1.7 all the way to the redline.

Not too high then

I just stuck a boost gauge on my vRS but foolishly bought a 20psi one and the thing is buzzing off the scale even though I fitted a little plastic regulator valve! I'm going to have to order another one from somewhere

You need one that goes to at least 2 bar - 20 PSI is not even 1.5 bar.

You need one that goes to at least 2 bar - 20 PSI is not even 1.5 bar.

Like the man says 2 bar at least, i had a spare HKS gauge but it was only 1.5 bar and went straight off the scale

14.5 psi = 1 bar if that helps
