installation not for the inexperience
Had a very experience electronic tech. install it. He had to call on bullydog support many times. He said several times it froze on him.The part# was not enter in system. When he call bullydog they said they had afew hundred like that. After about 5hr installation was completed.I can really tell the difference in all around performance. However keeping foot off of gas pedal maybe a problem.
totally worth it (gmc 2500 6.0)
I got the bully dog to try and increase my fuel mileage and give me a little more giddy up when I'm hooked to the trailer. Before the triple dog I was averaging 11 to 11.5 Mpg, maybe 8 with a trailer loaded down. Now I'm averaging 14 to 15 and 12ish with my trailer. Very good investment I'm glad I got that little bugger.
