Is it an early or late 99 injector if its early its the same as what you have. If its late you would need custom programming to work with the injectors.

what are the differences in them and would it be worth the gain if it could be done?

The difference is that the newer one is a split shot and the old one is asingle shot injector.

If you are looking to spend money on injectors IMO it would be more beneficial to look into some DIY stage 1's and custom programming

I agree 100%

The '97 Cali and 'early '99's had 120cc injectors but they are split shots also. Later 7.3's have 140cc, and DIY stage 1's will be 160cc.

The Early 99 injectors are 120cc split-shot's, his truck has 90cc single-shot's, they are not the same. I would also suggest you look into diy-injectors.com, I have a set of stage 2's and Jim Rose's product is awesome and affordable. He can turn your stock injectors into stage 1's for around $500.00, and the power gain will be huge!

like what was said they are not the same

you would need a chip with split shot burn on it and you would have to put a SD fuel system on the truck. the stock fuel system pusle's to much to run splits. plus splits are not better for making power.look into the diy injectors or just look into getting yours buildt bigger

Before jump the gun and start throwing out stuff.. I have a question.

If you have a 94 and running a 97 pcm, did you replace your injectors? All 97's I've seen had AB injectors and your engine had AA single shots. That would be a funky idle at best.

I think the 97's either had AA's or AB's. The Cali. trucks would have AB's which are Splits.
If he kept his stock AA's and installed a PCM out of a 97, as long as the 97 PCM isnt a Cali. truck PCM then he should be fine. But I'll let him do the talking. lol.
