I love this thread and all it covers , I check it every day to see what's next , with that said I don't drive full time but when I do I almost never use the jake , not that I don't like it but I don't think about it , but I'm sure I have used it before and someone thought I was showing off and I felt I was trying to run my truck the way I felt was best , but thats the great thing about this country we live in is for the most part we are able to run our equipment how we think is best , and yes I know there are clowns that don't know why they use jakes but there is a switch there so turn it on and leave it on , but without knowing all of you personally I don't believe that's the type of guys that visit here , as for detuning , retuning or what ever , in my business if a customer mine is unhappy with or feals like I did a poor job than they will find someone better than me next time , so again however someone wants to run his business is his to decided
