Guys, gimme a break. He posts videos on YouTube telling you how to repair your cars. The videos are free. You can see he runs a shop. If he sells parts and makes some money, that's why he's in business.

I didn't mean I haven't benefited from his videos but just about everything he sells has a video for purchase which gives complete details on how to install the produce. The video aren't free. I understand that and have no real complaints for I love capitalism.

I think he sold injector nozzles for years without mentioning that they need to be pop tested and shimmed to be installed correctly.

I won't speculate as to what he was thinking when he fail to talk about balancing them but I'd say he never ignored balancing when he installed a set in a customer's car.

He sells a PDF on his products page that demonstrates pop testing. He sells pop testers. He sells shims. I'm not sure what else you could want.

I've bought a couple of his kits. They are expensive for what they are, but having everything in one box with illustrated instructions and a lemon drop is sometimes worth the price.
