There is zero data out there to support any of the claims made concerning 12 port injectors. None. Aside from people's butt-dynos, and I've never been shown the NIST calibration stamp on a butt dyno so I don't trust them, especially given people are generally comparing brand new chinesium 12 port injectors vs their multi hundred thousand mile, multi decade old gunked up factory injectors.
Every time I have pressed Raffi about dyno testing his injectors he has evaded the question and not actually done it. The original claim was they make more power and low end torque. Then they were claimed to improve idle and throttle response. Then fuel economy. Every time something does not pan out or people ask for proof of things that the sellers know is not possible, the goalposts change.
I will believe it when someone proves - comparing new 1 or 4 hole injectors to new 12 hole - ANY of the above claims, using actual, calibrated test equipment and rigorous testing procedures. Until then it is bullshit and the sellers are just making money off of the uninformed masses by selling chinesium injectors.
A sucker born every minute.
I think this thread says it all. You really should go back and read it again, you were told several times about those injectors.
pretty much this.
Raffi sells crappy knockoff injectors from China. This has been well known for a long time. People still fall for it and still call it an "upgrade" which boggles my mind as missing and bucking do not constitute an upgrade as far as I am concerned.
Given that you have two sets that are both bunk and one set of stock ones that have no problems, had no problems when put back in in between chinesium junk sets, and had no problems originally, I would "upgrade" to the originals you took out and tell Raffi to piss up a rope. I will have to discuss having injector upgrade stickers made by one of the othermembers. No injector change necessary, just put the sticker on and enjoy your performance improvement. You can even tell people they're 36-hole injectors (if you own 6 jeeps, and count all the injectors.)
What's interesting in the pictures Alex posted, one injector is setup for a single intake valve and the other for multiple intake valves.
But they have the same part # stamped on them.
They're also different colors, which cracked me up. Apparently china doesn't realize that OEMs color code connectors and injectors and such so that the assemblers can easily tell if they're grabbing the right parts, not just 'cause they feel like making 24lb/hr injectors purple today instead of pink, for the hell of it.
