Never heard of them.
So they just rebuilt these injectors to exact factory specs? Or are they modified? I'm confused now, because your first post said "30+ injectors", but I'm not even sure what you meant by that in the first place.
Ok, well you need to get the exact specs.
If the injectors have been modified at all, you need to update the tuning to run them properly. Otherwise you're going to have more noise, smoke, etc from improper fueling, injection pressures, and timing. That is why they are noisy.
You need to find out if they are still split shot, or if they were converted to single shot. You also need to find out what cc's they flow, and the nozzle size (typically a % over stock). Once you get that info, then you need to contact whoever is tuning the truck, give them the injector specs, and send in the chip to have the tuning updated.
