Very clean, but not sure how much you can do in the tune it yourself arena. Seems to me that MSD does their self learn, but then has optional screens where you can go beyond that if you want. Might be worth a look....
Friend of mine is running it on his car now, waiting for some decent weather to see how it performs!!!! Think I still want something with a lot of tuning capability like your system.... Kind of a steep learning curve but I don't have much else planned anyhow!!!!!!!!!
