After seeing an instillation of a Bullydog system on a big turbo diesel truck I wondered how something like that would apply to a MB diesel. I was thinking of a small(safe,noticeable) amount into the intake with some sort of manual system(toggle switch, push button, WOT) just to help maintain speed going up mountains. Does anyone have any fist hand experience with propane and MB diesels(mine is a non-turbo 300cd)? Please share experience or opinions. thanks, andy.
