orange light is low boost, red is high.... twist the tripometer reset to switch from KLM to MI ..

So the red and orange ligh just come on and off its not like the tac gauge on a analog car how it goes right to left every time u hit the gas

Ok thanks I also read the link

Correct. The orange light "generally" comes on about 2# of boost, and the red one comes on "about" 6# of boost. Depending on the adjustments on the hobbs switch that controls them.

is it ok for it to red light on stock 86 buick 12lb boost?

I think the factory specs are 3psi yellow and 8psi red. useless.

will 12lbs be safe 92 oct factory chip ext?

will 12lbs be safe 92 oct factory chip ext?

I dont think anything above 12# is very safe with only 92 octane and especially with the high timing of he stock chip.
