Normal Fuel PSI?

Since replacing that low pressure fuel pump yesterday I am going to keep my fuel PSI gauge on the mini maxx.

What is normal at idle? Cruising speed?

I notice that when I am coasting down a hill, it is at 0. Cruise set at 67 it is about 9.2.

Are you talking about ICP on the minimaxx?

I have the ICP displayed. Is that not my fuel pressure? If not, which one is?

the ICP one is the rail pressure i believe. The other one is injector pulse width. The rail pressure (ICP) is the one you want to monitor.

I see 4.8 at idle. WOT i believe most tuners command 24.5.

OK. I need to check mine at idle then.

Sorry for the ignorance but what do you mean by "WOT", and what do you mean most tuners command 24.5??

WOT is wide open throttle. When you put the skinny pedal to the floor if you are maintaining railpressure you should see around 24.5

If you are cruising around 67 mph 9.2 seems about right. I will keep an eye on mine around 70 mph and report back to you. That sounds about right tho
