Re: Did anyone ever use an aftermarket wastegate actuator (phuz)

exactly. it takes a lot more air to hold 20psi of boost at 6k than it does at, say, 3k or 4k.

A tune will help, but ultimatly with the stock turbo, you won't be ablet o hold max boost through the entire rpm range.
I think modder tried a race actuator from FORGE that they said worked on "all volvos" but in the case of the R it didn't. don't think anyone makes one that is easilt capatible with the R, but I could be wrong.
