Fuel pressure too high after FRX install

My tests are at idle...

I cannot seem to get my fuel pressure below 66 psi after the frx install. I have tried all springs, to include the stock spring from the factory. I can go higher, into the 70s (black spring) and the stock spring brought me back into the upper 60s. I'm currently running the gold spring which is hitting 72 psi at idle.

I'd like to get the fuel pressure down to ~60psi

There is nothing wrong with 66psi at idle. When you are driving that psi will likely go down anyway.

You haven't done the fpr shim mod or anything like that have you? Are you sure you got the springs in place properly? Maybe you need to replace th fpr itself?
When I had mine, I put in a new fpr and the middle spring. I only hit 58-60 psi.

Replaced FPR components at the same time. Stock spring makes trick run like crap, though still shows upper 60s at idling. Could possibly be the gauge.

If you are sure everything installation wise is good, then I am not sure why your pressure would be this high. If you did not have issues with your guage before, not sure why it would act up now, but anything is possible. You should be good up to 70max, not sure why your truck would run like crap using stock spring. It shouldn't matter as long as you are above 50psi.
Does your pressure drop when you get on it? Wondering if it could be pump related?
