Hi there, is it safe to up boost on a sti v2 running standard ecu? if so what can i take it to safely? As i had to get my zero sports chip removed as it was causing the car to detonate and now it is dog slow. It's running about 0.9 bar (is this right) with the standard ecu and was 1.2bar with the chip. Also it is making 227bhp @ wheels which is about 270 at the crank is this quite good for a standard car? I was told that subarus are usually down slightly on the quoted output

Cheers Johnny.
