hey guys,
i picked up my vacuum gauge today, its a Speco boost/vac unit as its the only 2" i could find in black, only problem is it keeps telling me i need a turbo :P
took the gauge cluster cover off and mounted it from behind, i also hooked the illumination wires to the demist/fog light switch wiring directly under where i mounted it:
looks pretty stealthy in black
then i tested a few different places to hook the t piece for the vac line into, this is the only place i could get it to read properly:
what should i be aiming for for best economy?
at the moment its on -20in hg at idle, -25 during deceleration and between -20 and 0 during acceleration depending on throttle position
thanks for looking
