I wanna play with the "old folks" too - as I am one. Sometime I think - gimme a small block and a four barrel carb any day.
Actually I too am intrigued by what can be done with turobed 4 bangers. And leaning toward being a computer geek the tuning aspect of these cars is fascinating. Too bad there's a bit more downside than frying a mother board if you goof though.
The LS1/LS6 has LSedit. The blue oval boys are close with stang tuning, and the p1188 thread here is way interesting as is this thread on the SRT forumm:
