This is the end result of a few hours of work and $60 because I didn't have a 1/4" NPT tap in any of my kits. I could have done this for less-than $40. The BG products were donated to the cause.
The REASON you want to use 20 PSI is precisely because of how peak-hold type injectors work. The injector signal sends a 4v spike to open a peak-hold type injector quickly, then maintains its open condition with only 1 volt. Really, it's a current thing and there's a longer explanation, but that's it in a nutshell. When you put the injector in its operating pressure, it takes more than a AA battery to open it, but you don't want to sustain that much current with a momentary switch and your expensive injectors. This isn't in the video because this warning wouldn't be as clear. Unless you can simulate the injector pulse precisely, don't try it. 1.5v is enough to open it below its operating pressure. If you open it and THEN apply pressure, you can flow as much pressure as you can throw at it.
I don't discourage anyone from getting their injectors professionally cleaned and balanced, but in my case, I didn't feel that was necessary.
In my first video, I thanked the seller for these injectors and happy to know I got a great deal on high quality parts. My gratitude is even greater because I had problems with them. It gave me an opportunity to help others troubleshoot these kinds of problems when purchasing used parts. A different idiot might have blamed the seller for peddling crap, demanding their money back... but that would only be because they didn't even know what they were looking at.
This particular idiot knows what high quality parts RC injectors are and how to clean 'em. $250 + $60 still means I saved about $150 on a brand new set. We all benefit because I bought these and I'm grateful! Let the good times roll.

Leak down testing
I get a lot of questions via email and over at the forum about the steps to
take when you encounter a performance issue like my Subaru's hesitation
issue and I often feel like I sound like a broken record when I cover the
basic steps that I cover when encountering a situation like that. My main
point here is that if you have a performance problem and you're going to
throw parts at the problem start with the basics before you to off and
start replacing sensors that you suspect are a problem, if you don't have
evidence of a faulty sensor then don't start there start with the simple
tune up items and check for vacuum leaks and air leaks as I've shown here
and I believe you'll have better results and save yourself some money in
the process. In short the rule of KISS applies, Keep It Simple Stupid.
If you have questions about your own engine performance issues head over to
my website and either ask the search function or ask the forum, we'd be
happy to help.

Injector Circuit & Wiring Diagram
Injector Circuit & Wiring Diagram
Amazon Printed Books

Learn to test and analyze automotive fuel injector circuits from a wiring
diagram perspective. Fuel injectors are attached to the fuel rail. It is
very time consuming to detect and prove a clogged fuel injector. The
technician needs to disassemble the fuel rail, de-activate the fuel pump
and perform lengthy tests to prove the fault. However, there is another
way. Using current ramping techniques the technician is able to prove the
fuel injector without any disassembly at all. Get the scoop here and save

- Reinstall top cover
Car used in this video 2008 Malibu.
This procedure cannot be done like this on newer electronically controlled
throttle systems; otherwise, it may require re-calibration of the ECU
If you DO NOT have a manually controlled linkage cable from the accelerator
pedal on your vehicle, DO NOT attempt this procedure.

DIY Testing & build EFI Fuel Injector cleaner
In this video I detail some quick tests and some not-so-quick fixes.
A dirty or stuck injector is not usually a fatal problem for the part. You
can clean injectors yourself with a little ingenuity, or use an injector
cleaning service. With the method I'm using, you won't get a sheet that
measures how much fluid is flowing, but if you use the right solvent you
can at least remove whatever is blocking it so that it can flow like it did
when it was new.
So the journey begins.
