I have A 2012 with all the sinister deletes running XRT pro on tow tune timing set at 2. First issue is can't figure out how to get the no ATT(aggressive turbo) tune on I copied and pasted over old files and still have the same every time I tune the truck. Reason I want the no ATT is its using way to much pushing way to much boost I don't need. I use it as my daily driver I would put it on street tune but Afriad its to much for the stock clutch right no with the ATT on the tune. I can boost 37lbs and 25k rail pressure at about 2200 rpms going up a decent grade. That's empty. Idk if that's to much for it right now I don't have studs either. I had a 05 and would push 38lbs easy but was gradual boost not instant like this. Also my of rail pressure never went over 23k ever. Any insight would be awesome thanks in advance.

Your fine, good numbers across the board. Download the tune with less aggressive timing if your blowing past the tranny. I have some MCC tunes that throw down 36 at 1800……….ie max torque curve per Cummins, so let it eat!

What u mean with less timing? I was told only to keep timing at 2 when on tow setting then 3 or 4 when in street tune. I don't have a egt gauge yet will be here Friday. I also have tqr management turned off cause didn't get to put my south bend dd clutch in yet.

Well I can tell you as a owner of 2 sticks, do the clutch ASAP! Just adding exhaust and air filter will slip the stock clutch
