I have one of those trunk mount kits, looks to be a quality kit. The controler is not as basic as it appears, with the provided software and a laptop you can write a map for how much alky at what boost. And there are three different ways to reference the boost and air temp. Or you can ramp it in just by air temp/or air temp and boost/or boost only. I have not installed mine as to date, (winter project)got to get my race car together first. But I will let you know how it goes.
