Fitting Boost guage

[dub268]

So basically if i understand right,

Vac sender/guage cross red/red, black/black, green/green then run red to ignition 12v and black to earth. Job done?

that's they way i done it on mine and it works  ive had no need for buzz t piece either

Fitted it, ill upload pics to my build thread soon.

On idle its at -10 is that right ?

either that's what the gauge bottoms out at or you have a vac leak - i'd be inclined to go with the first option as that's exactly how our innovate boost logger behaves too - probably the same map sensors! Still it doesn't hurt to have a quick look for telltale grime around leaky vac pipes.

I installed the Vac line all way from FPR to guage pal. 1 piece line, tight at both ends

Engine vac leak dude. But to be missing 10hg it'd probably be some huuuuuge hole. Like i said most likely its just how the sensor works. I suppose one way to test is borrow an analogue boost gauge from someone for a few minutes and plug it into your vac line, see what it reads.

Ahh ok mate. Well im going to take it for a run on bypass tomorrow to see what it boosts upto. Guage reads 0 with engine off if that makes a difference.
