Going with too big of a TB will definitely cause problems like that. Though, for higher hp it's also a good idea to go a bit larger to reduce intake restriction. From my experience, with 6 cylinder motors and for the power level I'm aiming for a ~70mm TB should be just about right. If it was larger like 80-90mm then there would definitely be some negative effects as you described.
