If you were tuned for 23 than you should be fine, but if you were not id turn it down to where it was for the tune. You may actually be making less power or getting some knock. Some tuners like to advance timing to get power some increase the boost. Id do some logs and make sure your not getting any knock.

I will add this: It depends on how hard you drive the car. While that figure is considered safe and I drove my car that way for about 35K miles, eventually I had the #1 rod bearing fail. Luckily in my case it didn't put the rod through the side of the block.
My car had seen alot of track use, dyno time, etc. And when it did fail the bearing spun at low boost (about 7 psi) while going up a very slight hill cruising 70 mph on the freeway. The post-mortum revealed that the stock connecting rod bolts had stretched on the #1 rod leading to the failure.
My car had seen lots of hard use, but there is plenty of good evidence showing that increased performance is paid for with shortened engine life. On my car everything looked solid & ran well right up until the bearing spun - no warning.
