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.

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!
