It's hard to find any good info on the 2010-2012 6.7's. Most people are driving older 6.7's or 5.9's that regularly post here. There are some things that are different from the 07.5 and the 2011 that I have now. Parts info and availability are improving but at a slow pace. I'm sure there are people out there racing these units but if you just drive and pull a travel trailer like me then the information depends on who you talk to. I undrstand Smarty has a tuner now but it is detectable even when removed if the dealer checks for it. intakes have started to show up from other manufacturers like S&B that were not available when I first bought the 2011 last March. Drive pressures are high with the factory turbo's if you modify the engine but I understand there is a larger version that will allow you to keep the engine brake working now. both of my trucks ran hot as far as I'm concerned. 220 is and was normal temp on both trucks pulling or empty. 2011 is still stock for now but I intend to do the complete deletes before I take the trailer out again this year. I haven't decided on the turbo yet but if I do the turbo I'm going to put head studs in as well. Hope this will help you.

 

S&B On my 2012 and Mini Maxx And Sinister egr and cooler delete and 5 in turbo back exhaust to 6 inch aussie stacks. Runs super strong and sounds good for a 6.7
