Diesel Tuners
I received an email and video from Trailer Life about Bully Dog GT tuners for diesel engines. It all sounds good but I have been warned that the warranty would be voided if I use a tuner. Now I wonder if this is true. If so then I guess I will have to wait until my warranty is up. It is 699 bucks and I wonder if there is enough of a fuel economy savings to ever break even?
