My uncle has a 05 5500 chevy he bought a boost vavle an was wanting to put it on but the box says its for an 04, will it work? If not what is there to put on it for added boost. It already has edge juice, fass, an a fuel pressure race valve. Thanks

Are you talking about the PPE boost increase valve? If so, it is for the 01-04 LB7 trucks, not the VVT 04.5+ trucks. If the edge juice is not enough for him, tell him to get EFI Live.

^^x2 boost valves do nothing for lly(04.5 and up) engines

what do the boost valves do for a lb7??

fools the wastegate into thinking that there isn't enough boost, allows the turbo to spool up a little bit more before the wastegate opens
