gauges gone wild

[84gnturbo]

All of my gauges in my 84 gn are way off. At idle it says im at 4k-5k, my turbo meter says 5-8 lbs at idle, speedos off by at least 20mph and i dont know if the fuel gauge is right. Help! how can i fix this problem.

The boost gage/tach is an easy answer: those things were notoriously inaccurate when brand new. I had an 85 GN that would show 3-4 lbs boost in park! I believe Caspers (?) has the repair kit available for them, but unless you are really really good at soldering you maight want to just send them yours and let them repair it.
