Gary I may have a set of G codes floating around here you could have one and um...pop test it and show the differences
BTW whats up with that third pop tester???
BTW whats up with that third pop tester???
G codes are made and are sold today.the reason i bought them was because they are quality factory built stanadyne injectors built in Italy as is the ip.the other reason was because there are so many myths about them floating around the net but no actual facts.
i put them in and run a WOT test after removing a set of delphi BB codes.performance was improved and idle was smoother.
they make my 8k lb empty truck scoot right up to 80MPH without effort.i can't tell you they are better,worse,indifferent than any other injector or if they are emission based or not as i don't know.i do know however they are far superior than the readings iv read about on various forums.
if this helps,cool.if not,that's cool too.
i bought my new G codes here:

fuel economy is in my sig.
(sorry no dyno info.)
I am reading what you post and want to understand. What causes me to question what you have posted about removing the Bb codes and installing G codes is what condition were the Bb in when they came out. I have no dought your mileage went up and buttometer dyno told you of and icrease. But not knowing what condition the Bb were gives me no warm fuzzy feeling. I believe we need to install a new set of Bb codes. Then remove it and install a set of new G codes. Then we will have a difinative answer to these questions.
I find these recent posts very interesting. Stanadyne used to manufacture a lot of their stuff here in the U.S., but much of their manufacturing has been moved overseas, including China. I find it interesting that that web site is offering all kinds of letter codes, and that their prices are all over the map. It really makes me wonder if this stuff is current, or new old stock. If it is current, I'd question where it is being made, and if Stanadyne is actually making it. Lucas/CAV was original equipment nozzles on most IDI's from Ford. They were made in England or Italy. Italy is actually a kick-ass country when it comes to diesel stuff. They have been at it so long, it has made them a real center of manufacturing. CAV became Lucas, which became Delphi, so we have had great success with Delphi product, and availability has been very good this year. Considering how every 6.9 or 7.3 runs great on BB's, there is very little reason to offer anything else. One of the other dangers with other letter codes, is that just because there is a letter stamped on the nut, does not mean that is what it is. One almost needs to pull the part number off of the nozzle to verify what the injector actually is.
