Well if that company is stirring you that way chances are they aren't a dealer for RV that’s why they are pushing you onto the drag kit. I have done allot of searching in my "do a search for turbo" days and man no one really likes the drag. I'm using the Rev hard mani on my kit. Like JAN said don't just take a company's word for it. You can't recall there name that right there is not a good start to begin with.
