Hi, just wanted to know about the different setups you can have for a twin turbo rx7 (FD3S). I see some cars which have 2 dump valves fitted and some with just 1 :confused: . I was hoping some1 could explain it to me., the pros and cons etc etc. Any information is appreciated.

Thanks.

vta dump valves are not a prob as fuelling is map based and not maf based
