Default Electronic boost control or Increase turbo size

Hi All,

Now I would like to increase my Performance of my 2009 S80 2.5FT.

There are 2 possible option:

1- install electronic boost control
2- change new turbo

I had already shorten the wastegate actuator and I love the response of the car but I just need more Juice to just knock my head on the headrest.

Any suggestion which should I go for?

I am not sure if I install Boost control, will the ECU still be limiting my max boost?

Cheers guys

Hello Akabond

Thank you very mich for your advice.

I've already upgraded my polestar rom. Apart from that i've already done these:
Custom cat back
Custom downpipe
Heico spring
Bilstien b8 shock

Shorten wastegate actuator a little.

So now i am looking for further Mod and possible mod next is these 2 things
Either electronic boost controller or upsize the turbo. Or both.

My local garage suggest using TDO4HL-18t

So what do you guys think?
