Hi guys,
i just finished installed a Speco boost/vacuum gauge onto my 1993 Holden Barina (Suzuki Swift) after trying a few different places to tap the t piece in to the vac lines ive ended up with it here:
it seems to be hooked up ok. When i accelerate it goes up, the further down i push the accelerator pedal the closer to 0 it gets, and when decelerating it goes to around -25. But when idling it stays at -20, ive read it should be around -12 when idling, is this a problem with the gauge or my engine?
heres another couple of pics of the install for those interested:
thanks
