Over boost concern

[Mike Z]

Just got tags for my new-to-me '87 GN on Friday, and had it out driving today. At full throttle, I'm seeing the stock boost gauge pegged. I thought that the car was pretty much stock, but I shouldn't be seeing this level of boost. Or, is the gauge inaccurate?

Where should I go from here? I don't want any head gasket issues... Should I put a boost control on it, or are there things I should check?

1. The stock boost gauge is notoreously innacurate!!

2. It only goes to 15# anyway, which in most cases is somewhat safe.

But you'll probably want to invest in an aftermarket boost gauge to be safe.
