The thing is that i dont think im holding boost very well it will go up to 18psi 19 psi but it wont hold across till 6k when the turbo runs out of power

Chris, that is because of the size of the turbo. The stock K24 cannot move enough air to sustain that level of boost to redline. Now you are seeing the reasons why a turbo upgrade is profitable

no it will peak and then fall
before 6k

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.
