fuel pressure
I searched the archives but the system does not regard multiple word search words. So I have to post. What should the fuel pressure on my 87 be at idle and off idle ? I got a rail gauge on it and it seems a little high to me.
Thanks

I installed a gauge last winter and if I remember well, it is at 50 (3.4 bar)
In the shop manual, at idle speed with vacuum on pressure regulator: test pressure= 3.3 +- 0,2 bar.

If it's supercharged, what injectors are you using? If 30# then about 32ish psi with a Vortech super FMU is about right. If you are using Tim's baseline kit I think you are still using 19# injectors and you may have to ask him for tuning info. I'd think 50ish is right in the ballpark at idle, vaccum line disconnected.
