You have to understand one thing. The PCM is designed to meet the HP goal, if it over the HP goal, it will retard the timing, if it is under the HP goal, it will make adjustment to meet that goal if possible. So you need to take it off of PCM control.
I tried it once and loved it! I havent looked back ever since...
until I get my S3 PCM.
Wrong wrong wrong wrong wrong. The PCM will try and lower the boost pressure if it see's it is over the tq target, but the only thing that retards timing is KNOCK. My car is PCM controled boost and i see mid to high 30's for timing with no HOM as it is S1.
i agree that 28 degree's of timing is low, but that is because the temps are hot from the IC. The hotter the air the less aggressive the timing curve will be. Remember hot temps more boost less timing, cold temps less boost more timing. So cool the intake charge and watch the timing come up.
