You shouldn't drive like that. Your maf sensor is probably on it's way out, or you have leak between maf housing and turbo inlet. It is the cause of yours ignition retard, because engine uses ignition for 120% load when in reality it should use the 170% one, and because of the maf sensor you're running extremely lean!

If you're asking about the tune - iat limiter is never going to limit boost, there are some touched overboost diagnosis maps, and I'm wondering what was the intention on touching the optimal ignition maps. Driver's wish lambda is stock - car always drives on lambda 1 until component protection kicks in. The limp mode on overboost error is disabled. The load reduction on knock is touched at 110 celsius of iat!

If I were you, I would get it back to stock, fix the malfunctions, and then get a proper tune.
