As a Master-tech for Chevrolet for 17 years here is my one and only encounter with this company. A customer of mine Ordered a stock lb7 injector set. Along with cp3,pressure regulator,high pressure lines and he wanted new glow plugs. Did a compression test just to verify everything was good. Reseal the injector cups and I finally Get everything in the truck, 3 of 8 we re already at a balance rate of 2.0 or higher. There wasn t a single one without a balance rate less than 1.2. Checked everything possible With the tech2. Everything was on point accept the injectors. With the one year warranty 9 injectors went out due to balance rates over 4.5 and fuel knock. Having to go into the rocker covers 5 times and replace high pressure lines every time as recommended. Do not buy unless you really like working on your truck. Be sure and order a couple of master install kits if you do your eventually going to need them.
