6.4 With DPF Delete acting up

[08harleychipped]

My 08 250 has an SCT Livewire tuner with a DPF delete kit. I have had it on their for a month or so now, but recently the check engine light keeps coming on. As of today it is sitting because every time i decide to drive it, it starts acting up. Once the engine starts warming up the truck will sputter occasionally and spit white smoke mixed with plenty of black from the exhaust. Throttle seems to have odd response. I just changed the fuel filter a few weeks ago. I have no idea what the problem is and was wondering if there was anyone who could diagnose the problem before i have to run it back to the shop.

Sounds like egr cooler or valve, could be a programming glitch, try trans tune only dpf off tune see what happens, heard of the sct getting all effed up and that working lately...

it sounds like its trying to go into regen... I have heard of a few trucks doing this with tuners....

When I hit the throtte the rpm's jump back and forth and the truck crawls and stops and then crawls again. The smoke that came out blanketed the road too.

what have you tried to remedy it? do you have a CEL?

[greasltn]

You said the CEL cam on, what are the codes?

[08harleychipped]

The CEL did come on. I checked the dash readout for codes and the DTC codes are error lost communication with the TCM and the strategy codes are FS0L20 and TGJF4

my advice is to put it back to stock and go to the dealer and have them reset everything and then get some sensor sims from H&S before putting the delete back on...
