Measuring fuel pressure

[NHCharger]

When measuring fuel pressure should you test the engine under load or can you just measure while in park and revving the engine. Two buddies telling me totally opposite methods.

Hi Brian,

Best way is to measure the fuel pressure driving down the road under full throttle.

Thanks Ron. I figured the Chevy guy didn't know what he was talking about.

So who gets to sit on the core support and watch the gauge while the other floors it, you or the Mrs?
