LS2 Fuel Pump Duty Cycle 99.6%

The Fuel Pump Duty Cycle on my C6 LS2 is always at 99.6%.
Idle to wide open!
I was of the opinion this varied with throttle position.
Is this what I should be seeing?

No codes and engine runns great.

Is this a normal reading with the DiabloSport on a LS2 engine?

thats not the diablo, thats what the PCM is reporting.

Right Mike, but is this what I should be seeing.
No where in the Corvette service manual or the Diagnostics do I see any referral to Fuel Pump Duty Cycle %.

yeah, he's not questioning the predator data... he's wondering if the fuel pump on his car should be at 99.6% duty cycle all the time... or if there's something wrong with the pump maybe??

Since it appears NO one is up to speed on this, I will try to make a run this weekend and log my Fuel Pump Duty Cycle.
If I do, I'll let you know the results.

hey Jim, try posting over in corvetteforum.com....

I'd tend to think tho, since you have no issues whatsoever, that it's normal for your car...
