I had a Bully Dog for my Diesle truck and it worked great but Its not the hand held tuner that makes the 5 star superior its the tunes Mike from 5 star installs and from what I hear the customer service( I have not had to call him back). Normally a shop like Mikes has to pay a yearly fee to be able to install programs to each specific make of tuners, some larger shops do different brands like Bully Dog ect...not sure about Mike. SCT does make different tuners with displays and different options you might look at, I would call Mike and tell him what you are after.
