Bigger Motor Swap But Less Power

I swap out a '99 e7 427 and put in '99 e7 460hp. I'm running it with my stock 427 computer and turbo. Am I doing something wrong that I feel less power from my 460 motor. Any advice to help me fix this

The software and datafile in the EECU need to be changed to those for the 460 engine

The 427 was a hell of an engine. By comparison, most 460's are a dissapointment, at least, that's been mu experience. But getting the proper software for the hardware won't hurt. (may not help much, either)
