What Boost valve
 
What kind of boost valve are you guys running? I am upgrading to efi live and want to know what boost valve to get. I have a ppe is that good? or is somthing else better? Or do you even need one?? Thanks

danny told me he hit 35psi without a boost valve. sounds crazy to me. so ask him. but i'm probably gonna keep mine on there when i make the efi live switch. and mine is the PPE.

PPE does the work just fune, i ran it for a while, still trying new things to the air system

the kennedy boost valve is also a good one it is alot more but you can ajust according to your needs.

I've seen three LB7 wastegate tabs (the closing tap inside the housing) break off. I'm not sure if it's a defect or what , but you might watch out for it. I've still got one of the housings I think, I'll take some pictures of it!
