My experience was very positive. The system was set to add a small amount of propane to the intake ONLY under conditions of high turbo boost. So when you were in a hurry, you had a little extra power because the fuel mixture was richer since it had the traditional ECU controlled amount of diesel fuel plus the metered amount of propane. It was a "Bully Dog" brand system. Had a small, trunk mounted propane tank that was slightly smaller than a traditional BBQ tank and it was DOT approved.
