actully i have a 52 it off of a new volvo . they also have a pro 52 that comes ready to use on our trucks for the band clamp on the compressor,and with there adapter but i made all that for mine. it worked pretty well for the few mins i had it on my truck , then nitrous back fired and blew the compressor out the side , NOT GOOD! i only have 191dvs and a 0 plate right now but ordering 370 very soon. i guess im asking if any one else had ever tried one?
