Pick up the vag-com and make logs , and see the limiter value.Then search it in dump.The max IQ u can get is 55mg by pump soft and 70mg mechanical limit. I think ur original map make 46mg and 2290mbar turbo pressure.U can get more than 210hp with 55mg.

Cheers

Maybe depending on part numbers , i have a few custumers that i can inject 55mg. if u ask more like 65mg the car only inject de 46mg. and when i request only 55mg i get 55mg on log.The only way is cheating the pump to get more fuel .
