I will mount it in my own SRT-6 within a couple of weeks.
P.S. The Auttronic SM-4 has also a launch control feature

Not standalone then is it?
Haltech makes very for serious standalone's, however if you look at their prices, they better lol. Also bosch makes standalones. They offer features like cruise control, launch control, etc etc... You just have to pay extra.
