No its not a bad thing, i have a 2006 gmc sierra and it does the same thing. For some reason gmc and chevy trucks oil pressure gauge moves will accelerating. The pressure itself doesnt change just the gauge.

This is supposed to happen; higher RPM=higher oil volume oil pump moves. Mine idles around 45 and will peg the gauge at 80 psi when it gets cold up here. done it for 200,000 miles. i'd be more concerned if nothing happened when accelerating.

The oil gauge on my 2000 chevy silverado keeps going higher then 45 when i idle up and when i slow down it goes but to normal

It's normal for the gage to read higher when you give it gas. The oil pump is spinning faster creating more oil pressure. It should go back down to normal at a idle. Nothing really to be worried about. Thanks, Dusten
