Hi, trying to hook up an SAAS mechanical boost gauge.

But can only get vacume readings.When on boost only goes to zero. Idling bout -20

On my second new gauge now and it do the same thing ! rrrrrrrr.

Have obviously searched this and found no answer.

Have tried both the following with no joy;

" And just T it in between the intake manifold and BOV is probably easiest.

Or T it between intake manifold and fuel reg. "

is on an 03 xr6T ute with rapid V1 cooler.

Does that vacume fitting on manifold have a return valve in it on early NZ BA's ??

Can I put a fitting somewhere else perhaps ?

thx all :)

yes id like to know. hooked up a calibre boost gauge and reads about -20 on idle and only boosts to 0 and no more?

really frustrating me. the t piece is hooked in just before the blow off valve, on the BOV vac line...

cheers

All sorted had to actually drive it for it to register boost. Weird. Don't see why it wouldn't register when revving in neutral.
