Too many variables to make any blanket statements....... If you can put on a bigger throttle body, and use the EFI to make it idle and run through mid range well, then with big enough injectors for sure you are gonna get more peak HP at WOT with the bigger TB. Of course, you gotta have the cam, etc. to breathe the increased air.... and so on and so on.
We don't know what cam,headers, etc. that the OP has. So saying it will/won't do more HP is kinda like saying a bigger carb will not make more HP.. maybe it will and maybe it won't.
