Has anyone here tuned there 17+ 6.7 with all the epa garbage still in place?how did it do.

 

Here’s a pertinent thread...

Anyone using a banks derringer tuner?

 

I’m was thinking more like sct,or custom tuning

 

I have a bully dog BDX on my 17 6.7 and HATE IT! I've actually put the truck back to stock due to issues with the BDX programming that Bully Dog cannot figure out. Don't get me wrong, I loved the extra power but the CONSTANT regeneration and errors from it drove me crazy. If you drive any city streets the truck would regenerate anywhere from 50-150 miles causing the code P2459 to come up. The truck even had the same issue when driving on a 1000 mile highway trip (but it would regenerate randomly between every 100-200 miles).

I've talked to Bully Dog and they pulled all the info from the programmer and the computer and still no fix... Therefor I have a BDX sitting in the garage with no use.
