as im new to this more advice the better, is it worth turning up the boost on my turbo or leaving it as it is, if its a good idea how do i do this. i have a 55plate wrx (cypriat Import 261bhp)

 

Is the car Std if so it probley has a TD04, I wouldnt push that more then about 1.2-1.3Bar, well i didnt on mine.

If you want to up the Boost, you will need a remap so it all gets setup Propley.

Have you change the Exhaust or anythink like that?

If you are going for Boost ajustment i would say, to Upgrade the Exhaust system, Green Panel Filter on the std air box, the list can go on really, Sti Injectors, Walbro 255 fuel Pump. Colder Spark Plugs, Decats, Uprated Intercooler and so on
