My car has been running very well too under fuel+spark. I really need to find some time to get rid of these 415 cc/min injectors put the 780's back in and turn up the boost pressure on this 16G. I've never gone beyond 200 kPa or so, I think 220-230 kPa would be a good boost pressure for this turbo. Matt, what do you think would be a good advance to run at this boost pressure? If I had to guess, I'd say around 16 degrees at peak torque then slowly increase the timing to around 20 degrees at redline?

Also, what are you doing to monitor knock? I don't have any kind of knock monitoring system other than my ears.
