Ok so I have a 2008 6.7l 2500 both deletes, 4' turbo back exhaust with 8' tip, and a h&s xrt pro. I just updated the xrt pro and I thought it would havebetter things.. wrong.. I went from hot tune of 175hp to preformance tune with 120hp.. I can see Iit on the throttle which I have way less response from it and it hardly even smokes now.. I like the coal roaling when I have a dbag behind me tailgaiting me cuz it makes them stop really quick. Any ideas what I can do to make my smoke come back or if anyone has the old firmware for the xrt pro??
