It's TDS' VAFPR.

I had it set for 9 @ idle and 14 @ WOT.

I just had my Walbro 190 fuel pump put in, and now it runs at 12.5 at idle. Did yall have to tune down your regulator with the new pump?

Lucky you. Anyways you will most likely have to turn it down a bit. Aftermarket pumps can really push some fuel and any regulator is a rough geuss.

That's putting it mildly
