Fuel pressure should be set at 0 vacuum/Boost (@ atmospheric pressure). Set it with engine off, only running the fuel pump.
That is what I did. I turned the pump on using ECMlink and set the pressure to 37. I then set global/deadtime and then turned the car on. I checked the base fuel pressure by taking off the vacuum line to the FPR. the FP gauge was then reading 39 . I will change it sometime soon before I get into too much tuning. I have a lot to learn first.
Coldest thermostat I would run would be 180*. If you run anything much colder than that, oil temperature could possibly not come up to operating temperature.
This is why I am unsure what to do. I have read about many people suggesting running a thermostat 10* (170*) or even 20* (160*) cooler. The other suggest what you have suggested here....stick to stock and run the 180*. I do not know what to believe because both stock t-stat and cooler t-stat have have their advantages and disadvantages.
