I've seen that car up at killswitch. It's a KA-T setup. If it's cutting off under acceleration, I would recommend double checking the FMU to make sure it is functioning properly. If it is, then check your injectors. If the injectors and FMU are all working properly, upgrade the injectors and possibly fuel pump. KA's under boost and hard acceleration will starve themselves pretty quickly if the fuel delivery system isn't up to snuff.
