as you have increased boost you may have to take timing out... its a balancing act... too much boost too soon makes 1.8t's hot and they pull more timing top end

for what exactly?

All engines are different... you need to tune to its capabilities and thats not dictated by the parts you have bolted on, no two engines will be the same even if they have the same parts/turbo

Without logging EGT's, IAT's and everything else its hard to tell.

I read Dan recommends the BBT turbo's like k300 upto 1.4 bar, I expect they blow hot air above that and there is no gain.

edit:
@beachbuggy
Dan, did I quote you right? Or can these uprated bearings and step gapped seals usually be pushed higher
