Wondering if anyone on the board has an injector flow test machine and is willing to check them.
I have some Siemens 60's I need flow tested as I bought them used and was told they had been cleaned about 1000 miles ago but I need peace of mind.

If you go to https://www.turbobuick.com, and contact Chuck Leeper
He did mine 60# injectors as he check them out, clean them with new oil rings and also gave a before and after flow chart

I want to add one of these to my shop - https://smile.amazon.com/AUTOOL-Ultrasonic-Injector-Motorcycle-Automotive/dp/B07NYWH1QP/ref=sr_1_9?keywords=injector+cleaner+machine&qid=1642349035&sprefix=injector+cleaner+%2Caps%2C166&sr=8-9

Read the reviews and it might not last long

I've read reviews elsewhere and it seems to be a decent unit for cleaning and general testing. It's not going to flow accurately on any decent-sized injector as the pump can't keep up. Of course, they've probably gone to shit since I was looking quite some time ago.

When one of the locals watered the gas tank in my GN I took the injectors to a buddy who raced the turbo'd Hayabusa. He had a small ultrasonic cleaner. Threw them in overnite and they were fine. Think he spent about 100 bucks on it. He used it for old injectors that were plugged and they worked after.
-
I can recommend Injection Connection. They test every injector that comes in. He told me, the worst thing for his business was to rebuild good injectors.
I shipped my original GN injectors to him. All six failed at least one of his 3 tests. He said replacement for originals had not been available for decades. He rebuilt all. One of my guys has used him for some time. Large injectors.

I finally got the info I needed on the siemens 60lb injectors from the original purchaser.
I did my research and found him on my own but it took a while for him to respond.
They first guy originally purchased them as a flow matched set around 2008 and never cleaned them before he sold them.
He said also that the car was not heavily used so they don't have a shit ton of miles on them.
He told me he included the sales receipt with all the flow details to the 2nd guy.
The 2nd guy I bought them from lied and told me they were cleaned before he bought them. Said he never got any paper work for them. Wouldn't give me the guys name he bought them from. Said his name maybe was Chad which it wasn't. Some excuses included that he couldn't go back on Paypal far enough to Oct.2020 which I found out I could go back to Jan 2019 and also that all his emails were recently deleted. He didn't know who I was I guess.
Lesson learned I should have just bought them new and gone with my gut since I never buy used stuff.
BUT
One good thing though is that they are flow matched and came with a perfectly matched 5.7 TT chip for my configuration all shipped for only $215.
A little savings but I didn't need the headache.
Talked to Eric about the chip and got all the details about it and I only need to re-install one MAF screen.
I'm gonna send them to chuck for cleaning, and new filters and O-rings which is included with the cleaning.
