ok I know i should be getting a bigger exhaust before a tuner but I was wondering if I could run like a 40 hp tow tune with a stock exhaust on my 05 LLY I have the cat and muffler deleted on the stocker exhaust as well if it makes any difference besides sounding a little more gnarley. Thanks

 

Yeah you will be fine. What tuner you looking for or at?

 

Im thinking about buying a diablo sport predator since there decently cheap and I dont need anything over the top just need a bit more juice for the daily driver
