Fuel Pressure Test

Hi all, 99 Boxster Base. P1123...P1125 CEL's

Did fuel pressure test and results are:

Engine Off 3.3Bar

Idle: 3.1 Bar

Question, with engine off (after running and shut down) the fuel pressure was 2.6 Bars if I let it sit... it crept up to 3.4 Bars...... which is the accurate reading?

Also....when replacing the fuel rail cap on the schrader valve I over torqued it with my cheapo torque wrench and popped the top of the cap and scored the top of the fuel rail with the bottom of the cap totally trashing the cap. Is this an issue I have to worry about. The valve seemed good and didn't leak...only a slight score or scratch at the base. Can I just replace the cap and move on. Thanks V
