Yep as above....i have an edition 30 running at 370bhp, and i am running the OEM Audi s3 uprated divertor valv. The forge divertor valve actually DOES NOT work on the edition 30's. A great extra in addition to the OEM DV is a FOrge Actuator valve...it gives the 'woosh' effect of releasing turbo pressure which the OEM DV does not. It literally slots into the chain!! :-)
