the balance test works of the leakdown test passes. holds pressure for 1minute or lots more, and steady so you can pulse it an see the time it takes to drop to near zero PSI. (this test is crude flow rate test)
many times the leak down test fails,due to bad FPR/ or injector leaks or that silly check ball valve in the pump is bad.
making this test not easy unless lucky.
