    Hey guys recently got a VY l67. I've done a decent sized service since getting it. Done lim gaksets, replaced charger gasket, charger ubend gasket, tb gasket, PVC gasket, spark plugs, oil, coolant, thermostat and o2 sensors. My main concern is it still doesnt seem to pull a good amount of vacuum. Hears they're meant to pull around 20in. If anyone has any ideas please let me know, cheers!
