I used Jasons sps to set my boost to 9 and timing to 7. Ran plenty of logs and 7 is the max I can run. Corrections are simply too high on 8, 9 and 10. Thats with a forge fmic and 99ron fuel.
Quick enough most of the time but it sometimes feels like the boost is there and other times not quite so much. Going to purchase the liquid display guage so I can keep an eye on what the engines doing more often, going to work etc. Saves me carrying the laptop around with vagcom.
