Don't you have to return to stock first, then flash up to the new version?

yes i returned it to stock before i flashed and upgraded the firmware

Well, Im sure there are some gifted SCT users in here, me NOT being one of them, I'd call them this morning just to make sure you get it fixed correctly. They should be in there by 9am eastern.

O.K. so after work today my buddy and I took of the dpf and installed the dpf delete pipe and my dpf back exhaust with some minor cutting to the exhaust got it to fit. replaced the 3 sensors and the 1 pressure sensor and still have the CEL with the following codes
P246C; P2463; P2452; P1000; also im getting a heads up display saying "reduced engine power" yet everything feels the same as when I had the old firmware and 1.17 version loaded up on the livewire with the dpf still installed. Now how do I go about not having the CEL?

What version off road delete are you running 1.18 or 1.20? 1.20 is only DPF off so it just works, if you have 1.18 you need to go into engine options and select DPF off or off road(I don't remember how SCT words it). Those errors indicate that the DPF function is still ON!

I had the 1.17 loaded up until last night when I returned everything back to stock. Then I hooked the livewire back up to my computer and upgraded the firmware on it and loaded the 1.20. Then today while driving to work with the dpf still on I got my CEL. So after work I grabbed the DPF delete pipe along with the rest of my exhaust and headed to my buddies house where we installed it. I drove home with the CEL still on and then I tried flashing it again but yet it still has the CEL with the same codes as before. So now I'm just confused. Could I have a faulty livewire?
