PMR, You're going about it the right way, Increase breathing then boost. You will notice a big difference with the Dawes Just be sure to use good fuel and try an ECU reset.

Not meaning to sound ignorant but whats a dawes device? I have never heard of anything under that name down here in New Zealand and ive been messing around in the subaru fan club for quite some time...

Duczz,

It's basically a mechanical boost controller. You can get info here Dawes Devices as well as some install info at You've bought the thing, now what

There's loads of stuff on here re. Dawes, but this is where to start Dawes FAQ
