Taking long trip to Tenn, need fuel pressure advice.

If you adjust FP through the regulator you are only going to get the added fuel at WOT, when the O2's drop out.

If the car is lean at idle and midrange then it needs a larger injector, a larger fuel pump or maybe the meter recalibrated. The EEC will adapt and make the pulse width correct on the injectors to make the A/F correct.

It is well known that due to the fuel curve Pro-M has for a 24# and a Pro-M bullet they are lean at idle in many cases. It would not be present with a 30# inj or if you had a different meter, say an 80mm. Do a search and you may find some of the old threads on here and the Corral about the issue.

From what I remember the curves for a 19, 30, 36 are all the same, but for some reason it could not be acheived with a 24. I had that same issues and it went away when I swapped to a 76mm C&L.

I would make sure the car is set to 38PSI vac off and hit the road...
