Good addition for little money
First of if you have many mods to your truck you probably won’t notice any difference but on my stock lb7 it made a huge difference didn’t expect that much of a difference seems like a whole new animal

Looks nice
Can’t tell if it actually works as I don’t have a boost gauge but it looks good

Nice simple upgrade for the price
This product does not help produce more overall pressure, but rather more pressure at lower rpms. Not a game changer by any means but good upgrade for an lb7 at a good price

I am happy with my purchase though
This increased my boost a little bit, I think the price of the part reflects on the amount of performance you will actually feel, I am happy with my purchase though.

While I didn't get the "28-30psi" boost, and to be fair, I already am running a solid 22psi boost, I did see an increase to 24psi, and the truck "pulled" harder, and held the additional boost...this is an inexpensive way to pick up a couple of psi, and mildly boost performance...
