How much fuel pressure??
I did a quick search and found that the stock ITR fuel pressure at idle is around 42psi. How much pressure should I be running with JUN 3's and 12.1 compression??

Depends on your inectors. if you're running stock injectors, I'd say somewhere in the low 50psi range. I ran 52 to 53psi at idle last season, on Toda B's, milled head, stock bottom end. CR was probably in the low 11:1 range.

If you are running the stock ECU for a while, then you will need to lower the pressure to around 30psi (with vaccum hose off) or you will flod the engine at low rpm. When you get the ECU tuned you can raise the pressure back to around 45-50 psi and work with the ECU program to get the proper air/fuel mixture.
