Im running a tf035 on my gt and run 202.7hp at .9bar and full boost by bout 3200rpm. I used to run a td04 before this with 220hp but didnt suit my driving style, i now get full boost near 1000rpm quicker, it still pulls strong up to the redline and you dont have to change gear as much. Im not saying that the td04 was rubbish as it pulled like a train but why waste 1000rpm of boost for not much benefit
