That was the same thought when I had mine. I just did a simple wet kit and like Wags said, I did the plate. No need for extra stuff like injectors or anything crazy. I kept it mild around 100 and I did pull timing in the tune but I also did the resistor trick on the IAT to "enable" that so it was normal timing until I armed the kit. I'm sure there are much better solutions now than there were back 20ish years ago when the only tuning solution was LS1 Edit.
Just do your research and go with what you feel safe doing. Always keep in mind that it's a gamble, but you have that with any power adder.
