Splitport 3.8 stock injector size

I've had my Splitport in for a couple months but have not worked on it too much because of the cold (no garage ). Anyways, the only problem is its running rich. From info here and on the forums over at V6power.net, I believed a 2000 3.8 came with 19 lb injectors. With an adjustable pressure regulator I should have been able to get them down to 16 lbs. But even with the lowered pressure it was still rich.
The injector's part number YR3E-A4A did not come up on the web and the dealership was no help in determining the flow rating. I then called fiveomotorsport and he told me those are 24 lb and that he believes all 2000 and later 3.8s are 24 lb. So now I have to get some 19 pounders off eBay. I need the newer style injector because I changed the connectors on the harness to the new style.
So for everyone's information, the black injectors with the yellow band are 24 lb/hr. I think.

I thought the splitports came with 21#ers.


It's not a 97 Sport, it just looks like one!

so are you trying to run this on a stock computer then and thats why you're hacing problems? If that's the case just swap your stock 14# injectors on. The split-port came with 19#'s. If you lower the fuel pressure the only thing you're going to do is lose fuel at high RPM, run lean, and melt a piston. Keep your fuel pressure up around stock level or a few lbs until you can get a tune.

tan top - 14#
orange top - 19#
light blue - 24#
red - 30#
dark blue - 36#
bright green - 42#
