The LBZ or LMM pump is a lot better than the LB7 and LLY pump. Not exactly sure why...

The LBZ/LMM pump can support a significantly higher demand for fuel if the tuning is using it. I don't know how much better the ATS or II pump will be. I would guess that they are lightly modified LBZ/LMM pumps. I know there are some pumps out there that are significantly better than the stock units though, I think lots of guys run the Wicked Diesel stroker CP3's

The lbz and lmm pumps have more displacement than the lly and lb7. If you have the money and are looking into a bigger modded single I would go with a wicked diesel unit hands down. Pat has tested them and they will outflow the other pumps.

As far as I know Pat, and myself are the only ones who have actually ran them. I picked up almost 6 mph from switching to a WD CP3 from my stock LLY pump with LBZ Regulator.
