What trans setting with SCT?

Just did the DPF/DOC delete with SCT. Wasn't needing big power, and I tow a LOT, so I set it at the base 45hp, and left the trans stock. Should I use the "race" trans setting for towing, or leave it alone? '08 F350 4x4 dually.

The race shifting is going to firm up the shifts a good bit. Its not going to really matter if your running a 45hp tune in my opinion.

I was wondering the same thing as well. I have my pick up on the extreme setting just to get the mileage out of it, I hardly ever get in it beyond half throttle. Would the race trans setting give me any longevity and is it pretty abrupt with the shifting? Just curious...

The race shifting gives you firmer shifting.

The hard but firm "race" shifting IMO would help out the tranny on the long run.

i was wondering this too, I just got the sct and running stock dfp tunes right now. and Have it on the race setting on the tranny, was just worried if its bad for the tranny having it on this setting.

Also I am looking at pipes. If i just get the dpf delete would that be enough to run the big tunes? IF i get the full catback like from dpfdeletekits.com The AFE 4 inch back do i still need the dpf as well? it says turbo back...
Trying to not spend a grip on the pipes, but I do think the stock is ugly and quite.

The race setting is fine. It is going to be better on your transmission with the firm shifting. Might want to look in to getting the custom tuning package from Innovative diesel for your Livewire. That should really improve your shifting.

The AFE kit is not turbo back, it is downpipe back. It hooks to the stock downpipe.
