Fuel drops 5 psi

It's a LS1 with magnacharger at 7lbs, stock bottom end and racetronix fuel system. At full throttle the fuel pressure drops from 60 to 55. Is this a safe drop?

I'd say that's fine.

As long as your car was tuned with the Fuel pressure drop and your A/F is good then it is ok. But if your car was tuned with fuel pressure staying constant or climbing and now it is dropping then you might have a problem
