Upgrades for the URD 7th injector

So im working on getting a S/C for my 3.4 and while doing some research I found their is an upgrade kit for the 7th injector. Figured I would post it up for anyone who might be interested. But also to see if anyone knows exactly what the upgrade does? Kinda still a newb in the forced induction world.

Upgrade kit^^^^

 

TRD used to market a 7th injector kit.

If you have a TRD 7th injector kit and the computer has failed, or you bought it used and it will not plug into your truck, or you have a TRD 7th and you want to tuned it for better power, then you can install the URD UPGRADE kit for the TRD 7th injector kit.

If you do not already have a TRD 7th injector kit, this UPGRADE kit will be of no use to you.
