hanra Into the laaaake Member 1,532 Member For: 17y 10m 25d Gender: Male Location: Nrth Qld Posted 02/07/07 11:29 AM Share Posted 02/07/07 11:29 AM Ive noticed this Autometer Cobolt boost gauge gets fluttery when its in vacum about -15 to -20, and generally when im coasting off the throttle. I dont know if this is normal, or if its the gauge at fault, or something else wrong??? Where abouts would the boost gauge normally be plumed into the system? The car is stock, with a K&N filter.
