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.

Stock t-stat is 190*(ish). The 180* would give you a small advantage, but, IMO, it would be negligible.

There's no reason to run a colder thermostat unless you're having problems with your car running hot. And even then, there are other things you should do before jumping into a colder thermostat. Did you do a radiator flush? Is your rad cap holding pressure? What coolant mix are you running? Did you bleed the system properly? Does your rad core have a bunch of fins that are all bent up? Is your AC condenser still in the vehicle?

Plenty of stuff that can be addressed before running a really cold thermostat.

I'd recommend sticking with stock thermostat. When your car is running too hot and the thermostat is for sure opening the problem is a lack of heat exchange between the radiator. Make sure the radiator is clear of debris, make sure the coolant is flushed out well. Also make sure it is a 50/50 mix and that it isn't straight coolant. Check to make sure the radiator cap is holding correct pressure.

As far as tuning you should really be at 11:1. You need to post logs too, that is 1000x more useful then a screen shot. We can go into the log and see all the settings you have your car set to.
