I have a 09 si with a few mods and wanted to know the hassle kind of of the install and the perks of both superchargers (((CT AND KRAFTWERKS)) and which one would give the best bang for my buck ? Also both are bolt on as I've read do they both HAVE TO BE TUNED? Or can they run on stock ECu bc no one around tunes or dynos cars for me and my area.. I want something that I an install and not have to tow 200 miles to a dyno shop or get tuned so what's the best way to do it like that?

 

You have a lot of reading to do.
