I tried posting in the smarty sticky but got no reply.

Those of you who are running the smarty 67 which letter tuner are you running. I have a 2012 and have done the egr and dpf deletes. I'm running the "n" tune on "tow" tune and I'm not seeing the fuel milage that most are seeing with the mini max and raceme.

(23me) works well.

Also running the N-tune mileage seems to be the same as the older tunes and don't believe everything you read on here. For what it's worth mixed driving I see 14-16 and highway 17-19 with a best of 21 once of solid highway and nothing else. I wish UDC would become available to see what the custom guys could tweak out of it, but may just have to switch to EFI live.
