I dont know if this is the right place but I was just wondering if you guys new how much HP the stock replacement manifold produced over stock ??

 

I'm not sure what if gave us on its own but it really improved our spool and boost curves. We had bought an upgraded wastegate actuator to hold higher boost better but end up didn't needing it due to the header. We held 26psi perfect and made 403 whp on the stock fuel/ turbo and all the ETS goodies.
