has anyone run the H&S tuning on HOT with dpf still on.... like with the sensers unhooked... and if so did you notice a big differance when the dpf was removed with the same Hot tune

One would not run a non DPF tune with a DPF still installed. It would not matter if the EGT and Pressure Sensors were still connected or not. All that will happen is the DPF soot trap will be collect and building up exhaust soot till plugged up. I doubt much difference in performance if the DPF was cleaned before performing this idea.

X2. You're going to do more harm than good.

The DPF is the enemy. Get rid of it and you will unleash power and mileage. A tuner is near worthless on those trucks with the DPF still installed.

Im fully deleted with H&S at Hot and absolutely love the outcome! Never used the dpf enabled tunes, but getting 22+mpg now and the power is impressive. I will state just as an FYI, if you disable speed limiter, not only will you lose cruise control, but you also lose exhaust brake function ;). I have no muffler and run dual 6in stacks under the bed and it sounds AWESOME, especially when turbo cycles closed and "exhaust brake" engages.
