25 on the park meter for sapim race is about right. The park guage over reads. so tension is about 1300N maybe a shade more. If the dish is good and tensions even they are good to go. Make sure you stress relieve fully. Really squeeze pairs of spokes until your hand really hurt. Then place the hub axle on a block of wood and push down on the rim a few times (spin the wheel in between so you load it in different places then flip it and repeat). Then put it back in the jig and see how true it is. If you have stress relieved properly the wheel will not budge. This trick however requires a stiff wheel. If you are building with a shallow rim just squeeze the spokes and placing on a block of wood and pushing is a bad idea.
A fully stress relieved wheel will not ping on the first ride or the second. If it does you have not stress relieved properly. It is now though.
