Gentlemen I am currious as to what your true ground speed is on the diesel prowler? The reason I ask is when I first got mine I was dissapointed in its speed loved everything else but the speed. I talked to my dealer about it and he had it me bring it in. I do not know exaclty what he did but this thing gets it done now. Guestion is are you going to speed these machines up in the future or will I need to have my dealer speed them up?
