Default Acceleration hesitation

Hi guys so I have recently bought a M6 1999 corvette that has a 6.0 engine swap which was fully built by xpower performance and it has a 2 step launch control module and it drives fine with a twin disk clutch and tuned on 85 making 431hp. I am experiencing an acceleration hesitation at 2k rpm when i floor it it just studders as if the 2 step is being activated at 2k unless I gently give it gas it doesn't do that and it goes up on rpm, can anyone tell me what my problem could be ?
