What is the normal op temp. I want to say I saw around 4 or 8 when no gas with the increase rpm it gets up to 80 am I right.
I just installed the gauge and when I accelerate I get 100 psi and stays there but while not going anywhere it drops really slowly and to no less than 35 psi.
Is it the sender or gauge.
P.S. - I know for sure the gauge wiring is correct, I just did the boost and A/F ratio too.
Thanks.

 

Recheck - took it for a spin I have about 65 to 95 on acceleration and 15 at idle. These numbers sound much better.
