CJM: Ultimate 370z Fuel Pump Thread

I don't have a gauge on it yet since I couldn't fit CJ's tap at the dampener so not sure what psi it is idling at. Actually running around trying to find one locally that will work today.

I was getting spikes/surging when I first started it up with a base tune but that has gone away after Seb revised the tune a couple times. I'm still idling a touch high by maybe 100rpm or so but can't do the Ecutek idle learn with SD tuning, it just doesn't work.

Hopefully I can get a gauge on there today and see where things are at. I suppose that is what will actually dictate if I need to drill the regulator out or not.
