You'll probably get a bunch of flak here and I'm not sure how much response you'll get. Might want to post your question on one of the Cummins forums.
OTOH, I've had the same questions about using my Smarty Jr. Not sure what's best either!
Agreed that this isn't the place to ask for advice on modding your truck. I am surprised this post has lasted this long without all the internet nannies. You might try CumminsForum.com, or TDR. There are some good Facebook groups as well (at least there are a couple local in my area).
I have thought about tuning my 2012 since it is out of warranty, but the emissions issues are mainly what is holding me back since I live in an area that does emissions testing.
Scott, when I had my 03, I ran almost exclusively on SW2.
Thanks!
I used to run SW3 with a lighter TT but now we have one that weighs about 1k# more (9K) and I've since installed 50 HP injectors. So I've been running it on timing only and it tows fine. I do wonder if there's more or less timing on SW2 and 3. No one seems to know.
