Well worth it!
Bought this to clean out injectors on my 1.5l tubro engine build! Used ultrasonic fluid in Autools easy to use ultrasonic cleaner, and the miles of carbon build up came right off! Was then able to test the injectors in the test tubes and it was very easy to hook the wires up to the injector and click start! Easy as that, would highly recommend , no issues

Missing GM LTx GDI adapters, had to improvise. UltraSonic cleaner has no heating feature.
For GM LTx platforms there is no proper adapter, you have to find a fat o-ring to take up the space to the nearest adapter available in the kit as the OE o-ring is too small. Ultrasonic cleaner I thought came standard with a heating element, it does not. Also, GDI injectors run well over 1000Psi; this can only go up to 80-100PSI so while it can measure rate at low pressure there is no telling how much volume is used at it's original operating pressure. For the proper GDI tester runs several thousand dollars. For traditional injectors it works just fine.

Good Quality BUT
I bought this and it worked perfect for 20min.... The pump still works but now no flow to the fuel rail
