I just bought an '05 C3500 ! ton dually 3 months ago. I really love this thing! I've got about 4000 miles on it. Should I change the oil on it soon, or let service notice in the dash tell me when?
I've pulled a 10K trailer up Cajon Pass at 70 mph and Baker grade in the heat of the day (130+ ground temp)! This truck is stump puller! I've got a K&N in the stock air box and a Dyna Max diesel muffler on it.
My next step is I've got first run (direct bolt ons) 19.5 Alcoa Classics with 100K mile Michelins on order. This thing should run and look sweet!
I've got a friend that sells the Bully Dog stuff but, I have another friend that put "The Edge" unit in his '02 Max and really likes it. I just want to "kick it" about 50 to 100 horse so its reliable in the desert heat...which is the better unit?
Thanks for any suggestions.
