A larger TB will not help much since most of the engine's restriction is in the intakes themselves so giving more flow there doesn't really add more to the whole spectrum. The most you can really do easily to a 3.1 is port it out and do some other head work, and maybe dig into it and swap out the cam. But many will tell you that messing with a 3.1L MPFI engine is not worth it since a 3100 and 3400 will net you more bang for the buck but that also requires swapping in a different generation engine.
