Keep the stock one. The only aftermarket one made for the LB7 is by TTS and they want somewhere around 600 bucks for it.

IMO it's not worth it unless you are going for some big HP.

Thanks mods for deleting my post....

As far as more spoolup, you you will gain some, but it is still being restricted from the pedistal and turbo itself.
