I recently had my car dyno'd for the new PFC and I also had the AVC-R tweaked. My turbo died since then and now have a S1 stock turbo on. It's a S2, so I don't know how they differ if at all.
Problem is it always over boosts by ~.1 kg/cm, no matter what the duty. I've resorted to setting the boost to .5 kg/cm2 to get a peak of .62 kg/cm2.
The previous setting was .75 kg/cm2 @ 82% duty which it held rock solid just slightly tapering off at the top end.
Any ideas? Nothing has changed but the turbo. It's getting frustrating, spent about an hour last night on the
freeway messing with it...
