Re: 99 computer with 2001 engine? Don't the '99s have EGR? 2001s don't. I'd just get a 2001 PCM, especially if you're going to mod the engine. I've noticed I have a lot fewer PCM issues with my 2001 than earlier model LS1s do.

Re: 99 computer with 2001 engine? Yes, the 99 harness will work ok with the 2001 engine. Ideally you would want to reprogram the 99 computer to turn off the EGR (along with anything else you are not using) and match the flow rate of the larger 2001 injectors.
Other than that it will work ok.
