I'm looking to improve the power and fuel mileage on my 2012 Ram 6.7 Cummins, manual trans. What tuners would you guys recommend?

---

with emissions off or on? Also i can tell you from first had experience that you better save up for a clutch. our stock clutch is only good for stock power. I could slip mine with my smarty JR on the 40 hp setting not even trying.

There's a reason all the manual trans equipped trucks are derated over the autos from the factory. Read his reply again and let it soak it

my personal opinion is.... delete it all, or leave it the F alone! I also found "back in the day" that H&S seemed to have the delete and tune done very well, and had great customer support. IF you have emission testing..... your probably pretty much screwed. I work on these things daily and to be honest, I wouldn't own a 07-12 6.7 equipped truck. The 13-14 with def are actually starting to impress me again.

maybe I should send you a pm too!
