Just installed a/f gauge, 3rd bar RICH good enough?

![Question](https://www.rx7club.com/images/icons/icon5.gif)
I just installed my a/f gauge by autometer. at WOT most of the time, it reads the 3rd bar, sometimes the 4th bar RICH at about 7 psi. Even at 10 psi in 4th it was still at the 3rd bar RICH. Is that good enough? Also, can you tell if your car has upgraded injectors by the reading on the a/f gauge?
thanks
